It does not matter what dtd the second document conforms to as long as you know what its structure is so you can write correct templates for it. The only thing would be if its dtd refers to URLs or files that are not accessible to you (because they are on someone else's file system). >(By the way, this is off-topic, but does anybody happen to > know how I can just call a non-validating parser to confirm that a > document is well-formed? Well, you do not have to do anything - when you try to run a transform on it the processor will first parse it, and give you an error if it is not well-formed. > > One more complication: the additional source document is in 27 pieces, > so I was combining them using the internal subset on the DOCTYPE > line, like so: > > <!DOCTYPE OPR PUBLIC "-//xxx/DTD xxx//" "Oro-v315.dtd" [ > <!ENTITY efa SYSTEM "./ef/xmlout/efa.xml"> > ...] > > > &efa; > ... > > An old SGML trick which is still very handy, but here I'm concerned > that I'm no longer in pure well-formedness once I've put that DOCTYPE > line in there.

Normally it would not get validated, but entities declared in the internal subset ought to be understood as for any other xml file. Of course you would want to try it out with _your__ system and processor. Cheers, Tom P XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
