Comment (by ryandesign):

 Replying to [comment:11 Dave-Allured]:
 > And I have not seen an easy migration path for softwares like this one,
 that heavily depend on the former foundational `xercesc3` for XML support.
 Further thoughts?

 As I said in the ticket text, I recommend communicating with the
 developers to advise them to switch to something else. Scott said he has
 not attempted to bring the matter to attention of those developers using
 xerces-c in their projects, so if we want to reduce our dependence on
 xerces-c then it falls to us to bring it to their attention.

 Ports that require xerces-c can of course continue to depend on it.
