Basically it implements the subset implemented by James Clark in Jade.
For example DTDDECL is not supported.

Hum, I don't remember this option. At least using SGML_CATALOG_FILES

SGML catalog, their startup time and maintainance is really too high.

Yep, that's the place where this should be "fixed" then the distros will
follow. Note taht the latest Mandrake builds the XML catalogs when installing
resources and that the packages in Red Hat latest beta do the same.
