Michael Pizzo commented on ODATA-497:
-------------------------------------

I did a pass through [Protocol] [URL] [CSDL] {ATOM] and [JSON]. Still needs to be fixed in [ABNF].

> 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'
>    $filter=ChangedAt lt datetimeoffset'2013-09-02T00:00Z'
>    $filter=EndTime lt time'23:59'
>    $filter=ID eq guid'01234567-89ab-cdef-0123-456789abcdef'
>   ~/Tasks(guid'01234567-89ab-cdef-0123-456789abcdef')
> 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
