Question abot DTDDECL and SGMLDECL

Daniel Leidert · External Since: Feb 12, 2005 Posts: 279

Hi,

I hope, a few people are still reading this list Smile

My question: What
goes wrong? The docbook-xml SGML catalogs contain a DTDDECL entry

DTDDECL "-//OASIS//DTD DocBook XML V4.5//EN"
"/usr/share/xml/declaration/xml.dcl"

If I do a

onsgmls -E1 -wxml -wall -gues test-4.5.xml

with a simple DB 4.5 XML file, it fails. If I add a SGMLDECL entry:

SGMLDECL "/usr/share/xml/declaration/xml.dcl"

it succeeds. Why does it fail in the first case? The PUBIDs are the same
in the DTDDECL and the testfile DOCTYPE. If there is some documentation
out there, that can explain my question, please don't hesitate to point
me to it.

Regards, Daniel

Simply because the debian version was built with the config option
--disable-dtddecl. That was done for performance reasons, enabling DTDDECLs
makes opensp and openjade take literally ten to twenty times as long as with
it turned off. See bugs 138924 and 208042.

Thanks for the info. Would it make sense to mention this somewhere in
the onsgmls man-page? Under BUGS or in a section LIMITATIONS (following
the man-page how to)? This could also be a reasonable solution for
http://bugs.debian.org/345478.

Yes, it would. Thanks for the suggestion.
