Hi, Udesh,

according to XML 1-1 specification[1], your example does not adhere to
the grammar. Relevant grammar sections:

[3]   S   ::=   (#x20 | #x9 | #xD | #xA)+
[40]   STag   ::=   '<' Name (S Attribute)* S? '>'
[41]   Attribute   ::=    Name Eq AttValue

Important bit: (S Attribute)*. As you can see, Attribute can never
follow Attribute without a whitespace between them.

Maybe that W3C parser supports non-spaced attributes is coincidental?
Or maybe I am looking at the wrong grammar?
