Everyone is correct, it doesn't work. It is not Xindice, but rather
the XML:DB or DB:XML or something like that API that doesn't
support it. So until the API is updated, Xindice doesn't support
it. HOWEVER, this is not to say that you can't get back the
node that contains the attribute. I have nodes like:
<name first="mark" last="stang" />
And I do searches for "mark" or "stang" and they work, they just
return then entire node. So, you get more than you asked for.
And if you search for an attribute of the root node, then you can
get the entire document.

I have yet to find any bugs in the XPath queries :-).
