I think using the "AND" terminology is still confusing. Alternate 
proposal inline.

Q: forgot to ask that before -- are we confident that we don't need a 
caseless matching attribute here? note that in the real world, people 
frequently have both lower- and uppercase extensions.

I'd just say "comprises those resources matching the include pattern(s)."

"...compromises all resources except those matching the excluse pattern(s)."

I think it would be good to avoid examples using matching extensions -- 
this really *should* be done using matching on DAV:getcontenttype.
