What do you think about having multiple Org grammars that parse specific
parts of an Org file and treat the rest as text blobs?  The idea is that
small tools (on smartphones) could concentrate on (say) gathering and
using the info related to one of:
+ task management
+ tangled code
+ Org file options
+ etc.

How complete do you feel this grammar is?

Hmm.

Thanks for the effort! This could lead to Org developments on non-Enacs
platforms (smartphones & tablets)

I'll see if I can look at this -- it's been decades since I played with
grammars.
