Table Auto numbering template fails with namespaces but is fine otherwise

[Carlton Joseph <carlton.joseph@gmail.com>]

Hello Folks,

I have two question.
1 - Why does my table auto-numbering scheme not work with namespaces
2 - Is the way I do table numbering the recommended method

xsltproc -o test.html html.xsl test.dbk
works and generates tables numbers

xsltproc -o test_ns.html html_ns.xsl test.dbk
no table numbers are generated.

My file are at the end of this email.

I am guessing my template need to be specified with the namespace
and I do not know how to do that.

Thanks for your help in advance,
Carlton.
