OKidoki, maybe start with the first as it has a huge impact on the
implementation cost:

   TMQL Issue: predefined data types

   Impact on Language: very high
   Background

   At the moment, TMQL has a rather arbitrary choice of primitive data
   types: integer, URIs, decimals, datetimes, most of them cloned from
   the XML schema data types

        http://www.w3.org/TR/xmlschema-2/datatypes.html#typesystem
   	

   The question is which of these should be in the final standard.

   Structured Discussion

      ? should all types from XSD be understood?
        + very rich collection, strong big-vendor support
        + constants can be written 'naturally' (3 instead of "3"^xsd:integer)
      => also all XPath 2.0 functions and operators have to be supported
        - very expensive to produce for small developers
    
Any thoughts?
