Make type prefix optional for URL literals
------------------------------------------

                 Key: ODATA-497
                 URL: http://tools.oasis-open.org/issues/browse/ODATA-497
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: OData ABNF Construction Rules, OData URL Conventions 
    Affects Versions: V4.0_CS
         Environment: [Proposed]
            Reporter: Ralf Handl
             Fix For: V4.1_WD01


Currently we require literals for e.g. Date and DateTimeOffset to be prefixed with a type identifier, e.g.

   $filter=StartDate ge date'2013-09-02'

In most cases the type of the literal can be deduced from the context, e.g. type of other comparison operand. 

The only case in which this cannot be done is when comparing two literals, which is rare.

So we can make the prefixes at least optional, or even completely get rid of them
