|  Knowing that the DocBook DTD is an huge beast and can require
| as much as 3-4 Megabytes in the libxml2 DOM tree representation
| your results are perfectly normal.

FWIW, the DTD used by Website is considerably smaller. (Unless the
author is using 'website-full.dtd'.) The normal Website DTD is a
customization of the Simplified DocBook DTD which is only about 100
elements.

It may still be the case that loading 300 copies of the DTD is
problematic.

An alternative strategy would be to validate using RELAX NG (the
latest experimental Website distribution includes the schemas). This
way you can remove the DTD references altogether. And as an added
benefit, you get to use any darn namespace prefixes you like for the
embedded vocabularies (rddl, rss, etc.) that you might be using.

Just make sure that you *do* validate with something.

                                        Be seeing you,
