This is something that happens during XML parsing, not during XSLT
processing. Most XML parsers, if the document has a DOCTYPE, will try to
dereference it; and for XSLT processing this is pretty-well mandatory
because of the problem of entity references.

There are mechanisms (OASIS catalogs) that allow you to redirect the parser
to a local copy of the DTD, but you can't entirely avoid reading it except
by removing the reference to it.
