Hi Sijo.  Which version of the draft are you looking at?  The XQuery 
grammar clearly defines S as:

[158]           S          ::= [http://www.w3.org/TR/REC-xml#NT-S]

And later, when defining ignorable whitespace:

Whitespace characters are defined by [http://www.w3.org/TR/REC-xml#NT-S]

Certainly the intention is that the definition of whitespace use is the 
same.  If you think you know of something where this isn't the case, 
please post to the bug tracking system!

We could, though the draft is currently clear on this.
