Nothing wrong with that, but I just prefer the more general >solution as a rule (but I'm like that). Because MIME types can be >associated with notations (say by using the MIME type as the public or >system identifier for the notation), the two mechanisms can be complimentary. I think one of my problems with NOTATIONs in XML is that there has been no way of linking (F)PIs to system resources. I have realised (or re-realised) that this can be done through the CATALOG mechanism. Am I right, therefore, in thinking that use of NOTATION will often be accompanied by CATALOG entries? If so I am partially relieved. CATALOGs are NOT formally part of XML (though there is nothing forbidding them). They therefore seem to be potentially part of the *implementation* (and XML has always distanced itself from the implementation). I also used to dislike catalogs because they were one of the many files-that-could-get-lost when transmitting an SGML document to someone. If we use jar files (in Java) they can hold CATALOGs along with all the rest that we are going to have to deliver - stylesheets, schemas, DTDs and the rest. If this is the case then it relates nicely to our XML-DEV catalog approach. P.
