[Orgmode] Random tag-related thoughts

[Bastien]

Hi Carsten and list,

just a few midnight thoughts on tags.

0) regexp matching 

   Let's say we have :tag0: and :tag1: - then we want C-c \ to match
   all :tag.: - would that be possible?

1) numeric tagging

   Imagine we use numeric tags like :000: :001: 002: etc.  Sometimes
   and somehow we want to match tags between :001: and :X: (X being a
   number between 0 and 999:) - can we achieve this?

   (Actuallay i stumbled on this while tagging programming tasks with
   expected version numbers but was stuck because i couldn't look up
   for tags between two versions.)

2) grouping tags

   { tag1 tag2 } is for mutually exclusive tags

   What about [ tag1 tag2 (tag)] for grouping tags - "(tag)" being the
   tag-name of the group (i.e. matching all tags in this group)?
   
I'll stop here - was just musing around posibilities, not actual need.
But thought it might be interesting anyway.

Best,
