[erlang-questions] [Patch] XMERL Attributes without whitespaces

[Eranga Udesh]

Hi Motiejus,

It is not just W3C parser, but it seems PHP/Java XML parser(s) too support
attributes without spaces.

For one of our projects in Erlang, we had to customize xmerl, because their
existing XML parsers are supporting the XML syntax without whitespaces in
attributes. When validated the same XML in W3C, no errors shown, so being a
new solution, we had to comply to their existing XML syntax.
