I am very interested in automatic Typing of information components and think that this will be a very active area for the XML community. XML(SGML) entities (NOTATION) have traditionally used PUBLIC and FPIs (Formal Public Identifier) for adding type information. This works if there is a registry of FPIs for this purpose. Without it is not much use. My impression - and I'm happy to be corrected - is that there are few useful FPIs for Typing objects. Using a SYSTEM Id is subject to the problem of permanence and uniqueness of URLs. > >* The XLL mechanism (well, I should say the MIME mechanism really) is >based on the entity being self-identifying as to type (aided by >any additional attributes you like on the linking element). Unfortunately, not all targets of XLL HREFs will be self-identifying. This is true of local files and not-very-smart-servers. It is therefore useful for the author to be able to add MIME types to the target. As yet, MIME is not part of the XLL mechanism. I wish it was, and keep squeaking for it. If it isn't I suggest we use XDEV:MIME as a FUA 'frequently used attribute' in XML-LINKs. P.
