Re: customization stylesheet errors

[Alexander Kirillov <kirillov math sunysb edu>]

Hear is a typical problem: we needed to change chunking code to make
titlepage a separate chunk. So we just copied appropriate parts of
chunk-common.xsl from version 1.45 of the stylesheets and edited them.
But when we tried to use the same file as customization layer on top of
1.48, we get the following error: 

runtime error: file cvs/gnome-docu/gdp/xsl/chunk-common2.xsl line 36
element choose
 unregistered variable chunk.sections

because the chunking code has changed, there is no longer a file
chunk-common, and the  the variable chunk.sections which was used in
1.45 (and in our customization layer) is no longer used. :(

I am not sure there is a simple solution to the problem (We can't ask
for new stylesheets to be using the same structure and variables as the
old ones...) but if Norm has any suggestions, that would be great. E.g.
maybe he can specify some subset of templates/variables which are
considered "stable" (at least, that their name is not going to
change)and thus safe to use in customization layer)? What we really need
to customize is the chunking code and titlepage stuff. 

Thanks!
