I managed to trigger the bug in a non-trivial bit of xml parsing I was 
doing. Apologies that I don't have a test case, but the result of the 
CharData for
<TagName>Data Inside of Tag</TagName>
was
"TagNameide of Tag".
That is, it seemed like other parsing had overwritten the CharData.
Looking at the code, it seems that a slice from p.buf is being returned 
directly in xml.Parser.text(). When I changed xml.Parser.RawToken to
return CharData(data).Copy() instead of just CharData(data), the issue went 
away.

Nevermind, this bug is invalid. I didn't see that the documentation notes that tokens
are 
only valid until the next call to "Token()".
Sorry about that.
