The documents are small, but the DTD is very big (this is a DTD based
on DocBook + MathML). Currently, about 50 documents are included.
I wanted to post a followup, but hadn't had the time yet. FYI, I had
a discussion with Daniel on the LibXSLT mailing-list 10 days ago. In
short, for some reasons, the DTD structures are not reused each time
a new document is parsed. IMHO, this could be solved by some form of
cache (corresponding to the DTD + internal subset if any).
Technically, this bug could be regarded as a wishlist. But using so
much memory should be regarded as a bug IMHO, unless the other XSLT
processors have the same problem.
The title of the bug should be changed to something like "DTD
structures should be shared/cached in case of multiple inclusions"
(when possible, of course).
