As a heads up for other committers/developers, here's where I will be concentrating my efforts: 1. Completely implementing fo:marker/fo:retrieve-marker. I have attached a file that is based on the spec, and shows all FOs that may have markers as children (and those that explicitly may not, even as descendants, or there are special conditions). This attachment also indicates what areas are returned-by or generated by these FOs. This is important because fo:marker attaches to each _normal_ area returned by the parent FO (parent of the fo:marker), _and_ each non-normal area generated by the parent FO. So, in order to make fo:marker work in FOP, I intend to focus my attention on that list of FOs that are referenced in the attachment, and ensure that 'returned-by' is implemented. You can see the start of this in Block.java, ListBlock.java and ListItem.java. I am also implementing area traits 'generated-by', 'is-first' and 'is-last' as I go. For all of this, if you're interested, take a look at Area.java to see how things stand at present. This will all take a while, probably 2-4 weeks. It should be no/low impact on the work that anyone else is doing on the same FOs. With help from Karen we should see very useable marker support within a week. If it wasn't for the property thing it would be sort of OK now, at least for markers under fo:block. As more FOs in the list are supported then markers will just get more and more comprehensive 2. I'll be lending a hand to Peter West if and as required. I think his Tree class will definitely help all round, possibly with markers and I think definitely with keeps and space-specifier resolution. 3. Testing: I've spewed out code (and will continue, as indicated above) that deals with improvements on fo:page-sequence, and implementation of fo:marker/fo:retrieve-marker. Any time I pry free from the above will go to using Keiron's stuff and other scripts to provide tests for all of this, plus examples. Any questions, please ask.

Formatting Objects that may have markers, or may not May Have Markers: 1. fo:flow The fo:flow formatting object does not generate any areas. The fo:flow formatting object returns a sequence of areas created by concatenating the sequences of areas returned by each of the children of the fo:flow. The order of concatenation is the same order as the children are ordered under the fo:flow. Children are %block; 2. fo:block (%block;) The fo:block formatting object generates one or more normal block-areas. The fo:block returns these areas, any page-level-out-of-line areas, and any reference-level-out-of-line areas returned by the children of the fo:block. The fo:block also generates zero or more line-areas as children of the normal block-areas it returns. STATUS - 'returned-by' on normal block-areas implemented. 'is-first' and 'is-last'. 3. fo:block-container (not absolutely positioned) (%block;) The fo:block-container formatting object generates one or more viewport/reference pairs. The fo:block-container returns these areas and any page-level-out-of-line areas returned by the children of the fo:block-container. 4. fo:bidi-override The fo:bidi-override formatting object generates one or more normal inline-areas. The fo:bidi-override returns these areas, any page-level-out-of-line areas, and any reference-level-out-of-line areas returned by the children of the fo:bidi-override. 5. fo:inline The fo:inline formatting object generates one or more normal inline-areas. The fo:inline returns these areas, any page-level-out-of-line areas, and any reference-level-out-of-line areas returned by the children of the fo:inline. 6. fo:inline-container The fo:inline-container formatting object generates one or more viewport/reference pairs. The viewport-areas generated by the fo:inline-container are normal inline-level areas that use the large-allocation-rectangle. The fo:inline-container returns these areas and any page-level-out-of-line areas returned by the children of the fo:inline-container. 7. fo:table-and-caption (%block;) The fo:table-and-caption formatting object generates one or more normal block-areas. The fo:table-and-caption returns these areas, any page-level-out-of-line areas, and any reference-level-out-of-line areas returned by the children of the fo:table-and-caption. 8. fo:table (%block;) The fo:table formatting object generates and returns one or more normal block-areas. In addition the fo:table returns any page-level-out-of-line areas, and any reference-level-out-of-line areas returned by the children of the fo:table. 9. fo:table-caption The fo:table-caption formatting object generates one or more normal reference-areas. The fo:table-caption returns these reference-areas and any page-level-out-of-line areas returned by the children of the fo:table-caption. 10. fo:table-header The fo:table-header formatting object does not generate any areas. The fo:table-header formatting object returns the sequence of areas created by concatenating the sequences of areas returned by each of the children of the fo:table-header. 11. fo:table-footer The fo:table-footer formatting object does not generate any areas. The fo:table-footer formatting object returns the sequence of areas created by concatenating the sequences of areas returned by each of the children of the fo:table-footer. 12. fo:table-body The fo:table-body formatting object does not generate any areas. The fo:table-body formatting object returns the sequence of areas created by concatenating the sequences of areas returned by each of the children of the fo:table-body. 13. fo:table-cell The fo:table-cell formatting object generates one or more normal reference-areas. The fo:table-cell returns these reference-areas and any page-level-out-of-line areas returned by the children of the fo:table-cell. 14. fo:list-block (%block;) The fo:list-block formatting object generates one or more normal block-areas. The fo:list-block returns these areas, any page-level-out-of-line areas, and any reference-level-out-of-line areas returned by the children of the fo:list-block. STATUS - 'returned-by' on normal block-areas implemented. 'is-first' and 'is-last'. 15. fo:list-item The fo:list-item formatting object generates one or more normal block-areas. The fo:list-item returns these areas, any page-level-out-of-line areas, and any reference-level-out-of-line areas returned by the children of the fo:list-item. STATUS - 'returned-by' on normal block-areas implemented. 'is-first' and 'is-last'. 16. fo:list-item-label The fo:list-item-label formatting object does not generate any areas. The fo:list-item-label formatting object returns the sequence of areas created by concatenating the sequences of areas returned by each of the children of the fo:list-item-label. 17. fo:list-item-body The fo:list-item-body formatting object does not generate any areas. The fo:list-item-body formatting object returns the sequence of areas created by concatenating the sequences of areas returned by each of the children of the fo:list-item-body. 18. fo:basic-link The fo:basic-link formatting object generates one or more normal inline-areas. The fo:basic-link returns these areas, any page-level-out-of-line areas, and any reference-level-out-of-line areas returned by the children of the fo:basic-link. 19. fo:wrapper The fo:wrapper formatting object does not generate any areas. The fo:wrapper formatting object returns the sequence of areas created by concatenating the sequences of areas returned by each of the children of the fo:wrapper. May Not Contain Markers: 1. fo:title - not as descendant 2. fo:leader 3. fo:multi-case 4. fo:float 5. fo:footnote
