relax-ng empty named pattern

Hi All,

Is there a way to define an empty named pattern? Here's the use-case.

I'm trying to use relax-ng to specify an extendable schema.
Basically, people should be able to tack on whatever they like to a
core set of elements/attributes provided their extensions are in a
different namespace.

It would be nice if I could split it up into

core.rnc
ext-1.rnc
ext-2.rnc

so that a final schema could be made from just doing

include "core.rnc"
include "ext-2.rnc"

which would allow elements/attributes from ext-2 but not ext-1.

I thought I could do this by adding the named pattern "extension" to
each element defined in core.rnc. ext-1 etc could then redefine
extension accordingly.

If there's a better a way to accomplish similar goals, I'd be
interested in hearing them too.

Cheers,
Andy

My website is made in flash. I have a dynamic image gallery within. How flash knows what to load into my gallery is it refers to my .xml document. Within flash, it displays the picture, and then in the desc_txt, that is the object that loads in the text description from the .xml file. For some reason when the .xml loads the descriptions in, it does not recognize punctuation correctly. I'm not that familiar with xml, and I hate to just leave out...
