Agreed. But do dynamically added ElementMappings actually work, i.e., can we actually attach an ElementMapping to FOP without changing FOP code? To see how dynamic discovery/run-time addition of ElementMappings might work, I looked at SVGElementMapping and ExtensionElementMapping, two of the three already hardcoded. SVGElementMapping, for example, includes these libraries: import org.apache.fop.fo.FONode; import org.apache.fop.fo.ElementMapping; import org.apache.fop.fo.FOTreeBuilder; ExtensionElementMapping includes a Bookmark FO, which needs these libraries: import org.apache.fop.layoutmgr.LayoutHandler; import org.apache.fop.fo.FONode; import org.apache.fop.area.AreaTree; ElementMappings appear just too wedded to the application (definition and semantics) to be able to be dynamically added run-time to FOP. Even compiling such classes separately appears difficult. > Please explain > why this is a > prerequisite for the proposed move. > Actually, it's not, but it might defeat some of the goals of encapsulation. We can indeed keep this functionality in FOTreeBuilder--"dynamic discovery" of ElementMappings could be carried out by FOTreeBuilder, also, for run-time additions, one can call from code: myFOTreeBuilder.AddElementMapping(...); After the new API is nailed down, we may have similar versions of these functions back into FOTreeBuilder anyway, in particular to add/remove/modify *already hardcoded* ElementMappings for speed optimizations, etc, from the public API. But this is a separate issue--here, I would like the committers to think about whether they would like *dynamically* added ElementMappings in 1.0--my inclination--not much more than that--is "no" right now because I don't see how the current implementation of them can work. > > Here's my +1. > > I'll abstain pending further clarification. > Your current 0/+1 is noted...Feel free to change either upon further review.
