Colons in IDs

[Justin Lipton <ju...@ns.xn.com.au>]

Hi,

I'm curious about the use of the colon character (":") in IDs -
As far as I can tell the spec says that they are permitted but not 
recommended.
Xerces 1.4.0's XMLCharacterProperties.validName method returns true for
IDs containing ||colons - yet when the document is parsed an error is 
returned.

Anyone know the status on the use of colons in IDs?

Thanks,
Justin.

Which spec? ;)
XML Schema spec requires IDs to be of type NCName that forbits the use
of ":".
XML 1.0 spec, on the other hand, defines IDs of type Name, allowing
colon char.

XMLCharactersProperties conforms to XML 1.0.
However, it is an error for XML Schema to have an ID with colon char.
