I did some net archaeology: This was initially added to document-v11 DTD around 2003-03-20, i gather as part of the alignment with xhtml at the time. Soon after, the DTD changes since Forrest-0.4 were removed and the new document-v12 was commenced in CVS on 2003-04-24: http://marc.info/?l=forrest-dev&m=105115903415487 which did contain a comment about it.
The comment is also listed at the end of our example documents, e.g.: http://forrest.apache.org/dtdx/document-v20.html#changes-12 viz: "doc-v12 enhances doc-v11 by relaxing various restrictions that were found to be unnecessary. * Links ((link|jump|fork) and inline elements (br|img|icon|acronym) are allowed inside title. * ..." -David Sjur Moshagen wrote: > Hello all, > > I just noticed a discrepancy between the dtd and the actual rendering in the > default (and possibly all) skins for the title element.
