Subject: [ruby-talk:26003] Re: REXML parser bug(?)

I also might have found a bug in some REXM regex:
-----------------------IRB--------
irb(main):001:0> require 'rexml/document'
true
irb(main):002:0> doc = REXML::Document.new '<foo><bar.baz/></foo>'
[...]
irb(main):003:0> doc.to_s
"<foo>\n  <bar/>\n</foo>"
irb(main):004:0>
---------------------------
instead of
"<foo>\n  <bar.baz/>\n</foo>"

http://www.w3.org/TR/REC-xml.html#NT-Name
[4]    NameChar    ::=    Letter | Digit | '.' | '-' | '_' | ':' | 
CombiningChar | Extender
[5]    Name    ::=    (Letter | '_' | ':') (NameChar)*

So element names including a '.' seem to be well-formed, and should be 
handled.
