And I disagree with both of you :-) The problem with dereferencing either the namespace URI or the schemaLocation attribute is that it means the _author_ of the XML document is providing explicit instructions on how to locate the schema. Unfortunately, this author may have no understanding of the environment of the _reader_ of the XML document. The schema location used by the XML author may be inaccessible to the reader, and this reader should not have to resort to editing the XML document before (s)he can make sense of it. I don't object to URI dereferencing as a fallback if the reader has not given more explicit instructions, but the primary method should be for the reader to "install" a schema locally, and for XML processing software then to "know" where to find the schema information for the corresponding namespace. -- Cheers, John *************************************************************************** This is xml-dev, the mailing list for XML developers.
