Subject: Primative literals in URLs


I have a question regarding the use of primitive literals in URLs

 

In the OData 2 and 3 specs the definition of decimal and double literals define that the literal values must have a suffix of m and d respectively.  As best as I can tell from those specs, the suffixes were required.  However the sample services on OData.org do not required the suffixes.

 

This was the ABNF from the v2 spec

 

decimalUriLiteral = decimalLiteral ("M"/"m")

decimalLiteral = sign 1*29DIGIT  ["." 1*29DIGIT]

 

Next I look at the OData 4 spec and the ABNF for the decimal and double literals do not show the m or d suffixes at all yet the sample v4 services on OData.org do allow the m and d suffixes for decimal and double literals.

 

Here is the ABNF from the v4 spec

 

decimalValue = [SIGN] 1*DIGIT ["." 1*DIGIT]

 

From this, I am inferring that the use of the literal suffixes is optional.  Is that true?  Is there somewhere in the OData v4 spec that defines the literal suffixes that are allowed?

 

Thanks

Mark
