docbook v4.1.2 missing "catalog.xml". broken?

[PGNet <pgnet.trash+oasis@gmail.com>]

i've DL'd (from http://www.docbook.org/xml) xml catalogs on OSX,

	cd /usr/local/share/docbook/xml
	ls -al
		drwxr-xr-x 16 root wheel 544 2008-12-21 15:46 4.1.2/
		drwxr-xr-x 15 root wheel 510 2008-12-21 15:46 4.2/
		drwxr-xr-x 16 root wheel 544 2008-12-21 15:46 4.3/
		drwxr-xr-x 16 root wheel 544 2008-12-21 15:46 4.4/
		drwxr-xr-x 16 root wheel 544 2008-12-21 15:46 4.5/

and created a catalog file,

	cat /usr/local/etc/xml/catalog
		<?xml version="1.0"?>
		<!DOCTYPE catalog PUBLIC "-//OASIS//DTD Entity Resolution XML
Catalog V1.0//EN"
"http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd";>
		<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">
		  <nextCatalog catalog="file:///usr/local/share/docbook/xml/4.5/catalog.xml"/>
		  <nextCatalog catalog="file:///usr/local/share/docbook/xml/4.4/catalog.xml"/>
		  <nextCatalog catalog="file:///usr/local/share/docbook/xml/4.3/catalog.xml"/>
		  <nextCatalog catalog="file:///usr/local/share/docbook/xml/4.2/catalog.xml"/>
		  <nextCatalog
catalog="file:///usr/local/share/docbook/xml/4.1.2/catalog.xml"/>
		  <nextCatalog
catalog="file:///usr/local/share/docbook/xsl/1.74.0/catalog.xml"/>
		  <rewriteURI
uriStartString="http://docbook.sourceforge.net/release/xsl/current/";
rewritePrefix="file:///usr/local/share/docbook/xsl/1.74.0"/>
		</catalog>

validating, v4.5 works ok,

	xmlcatalog -v /usr/local/etc/xml/catalog \
	"-//OASIS//DTD DocBook XML V4.5//EN"  \
	http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd
	
		file:///usr/local/share/docbook/xml/4.5/catalog.xml added to file hash

		Catalogs cleanup

v4.4, v4.3 & v4.2 are also ok.

but not 4.1.2,

	xmlcatalog -v /usr/local/etc/xml/catalog \
	"-//OASIS//DTD DocBook XML V4.1.2//EN"  \
	http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd

		No entry for URI http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd
		Catalogs cleanup

checking, I find that 'catalog.xml' is missing from the 4.1.2 DL ...

	cd /usr/local/share/docbook/xml
	ls -al */catalog.xml

which, i believe, explains the failure ...

for 'just' docbook usage, i understand that I caould simply switch to
one of the catalogs that validate correctly ... but, in building
"glib-2.19.2 --enable-gtk-doc ...", it specifically checks (and fails)
for v4.1.2,

	...
	  dnl check for DocBook DTD and stylesheets in the local catalog.
	  JH_CHECK_XML_CATALOG([-//OASIS//DTD DocBook XML V4.1.2//EN],
		 [DocBook XML DTD V4.1.2],,enable_man=no)
	  JH_CHECK_XML_CATALOG([http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl],
		 [DocBook XSL Stylesheets],,enable_man=no)
	fi
	...

Checking with the glib 'folks', that version dependency can't be
changed -- and the claim is that the docbook DL's 'packaging' for
v4.1.2 is broken.

can this be fixed in the online source ? or, is ther something else wrong here?

Thanks.
