[ragel-users] Help with grammar of XML

[Iñaki Baz Castillo]

Hi, I've terminating a Ragel parser and to finish it I just must understand 
the following XML grammar as appears in:
  http://www.w3.org/TR/REC-xml/#NT-AttValue


 AttValue ::= '"' ([^<&"] | Reference)* '"' |  "'" ([^<&'] | Reference)* "'"

Could I know which would be the equivalent to [^<&"] in Ragel grammar?
The problem is that I¡m not 100% sure of what [^<&"] means in the XML grammar 
as it's not BNF which I'm used to.

Does [^<&"] means "any symbol but '<', '&' and '"'?

Thanks a lot.
