I have some notes on topics I'm thinking about....  This could work as
an agenda, I suppose.   I've added numbers...

================


      syntax choices

      [1]  * BAREWORDS - if they might become a defined term later (eg
             NAF) then it silently, sometimes undetectably, changes
             the meaning of existing documents.     So best to have
	     a declarations for local, maybe alias.
             (also, okay to have variable names declared instead of
             prefixed with ?)

      [2]  * infix operators -> parens
             parens -> ambiguity in:
                      p(a b (c+d) e(c+d) f (c+d))
             resolve with either
                      -> delimiters between all terms and formulas
                         (comma in arguments, semicolon/period in group?)
                      -> care about the space before an lparen 

      [3]  * QNAME, CURIES, and BARE_IRIs
                 disallow ()[]{} which are allowed in URIs
                 but allow - + = , ...           
                 it's a curie if the part before the colon is
                     defined via a prefix declaration; otherwise
                     it's a URI.

      [4]  * string literals (quoting), comments, numeric literals

      [5]  * MPS design: add anything that:
                -- I know how to parse comfortably
                -- has a well-defined abstract syntax (thus xml syntax)
                -- someone in the WG really wants and plans to use
                -- no one in the WG expects to want to mean something else
             
      [6]  * keep formula (boolean-expressions) separate in grammar
             from forms/terms (object-expressions).  Frees = for use
             in named arguments....
             [ maybe use use { } for reified formulas ]

      [7]  * frames as terms, nested frames, ...

[8]   schema-checking the parse tree...  dialect identification.

[9]   "include"

[10]  str-less-than ?
