[xsl] organization for large numbers of templates

[Brian Chrisman <incubus@xxxxxxxxxxxxxx>]

I'm wondering if the issue of organizing relatively large numbers of
templates.  Currently I have a reasonably maintainable XSLt code base,
but as I add templates, I tend to lump them into libraries by functionality.

Are there any standards, specs, or ideas on formalizing groupings of templates
much like Object Oriented Programming has grouped functions/methods into classes
etc?

I know I can kind of do this on my own, and have been doing so.. I'm just 
wondering if there's a directive or recommendation out there for such.

thanks,
Brian Chrisman
