[Steve Newcomb on AFs] >When looking at such an element, select the attribute that >corresponds to the meta DTD you're interested in interpreting the >element as conforming to; the value of that attribute is the tagname >for all purposes of that meta DTD.) > In other words, (as I have said before, years ago on comp.text.sgml), there is nothing "meta" about meta DTDs. They are essentially, a device for simple one-to-one mappings of element type name to element type name with some extra bells on. In my world, this facility fails the "so what" test. Oh how I wish the real world were so simple, that a basic mapping system sufficed to get real work done. I cannot understand why people think that this capability solves so many real world problems. It doesn't in my experience. Simple mapping of source elememt type name to destination element type name makes up about 0.00001% of what I do in SGML/XML processing work. The other 99.00009% is made up of re-arranging sub-trees, collapsing strucures, expanding structures, hoisting content to attribute, dropping attributes to data content etc. etc. The declarative syntax of XSLT is a lot closer to the money for my work as it goes beyond simple element mapping and sub-tree pruning. Not that XSLT does not have its problems from my perspective but that is a different rant:-) regards, http://www.pyxie.org - an Open Source XML Processing library for Python *************************************************************************** This is xml-dev, the mailing list for XML developers.
