Well, I'd say that an XML name was started with an invalid character.

'%' is not a legal name character (where 'name character' means
something that can be part of a tag, or in SGML terms part of a GI). 
If the parser *did* manage to choke down a tag with the name "%", it
would then choke on an attribute that starts with an illegal character
('this), then on the lack of an equals sign following the attribute,
then on the lack of a value following the missing equals sign.  It
would proceed to do the same, without having the problem of the illegal
initial character for the remaining two simple attributes ("is" and
"asp"), and would barf again on the attribute called "%".  Finally, if
you could force it to swallow that much grotesquely ill-formed XML, it
would barf again because the tag <%> does not have a corresponding end
tag </%>.

ASP syntax is not legal XML.  Turn it into legal XML before you hand it
to an XML processor (someone else may be able to suggest if there's an
alternative ASP syntax that is legal XML; there is for JSP, which is
basically Sun chasing ASP's taillights).

But really, the error message is quite adequate to diagnose the
problem.  Please forgive me if I'm taking too much amusement from it.
