So I think PIs should >look like > ><?name att1="val1" att2="val2" ...?> I'm not sure how your second sentence follows. Why not have XML as the notation (that is, XML-handling processors should operate on this PI) and still have a "GI" that indicates the subclass of XML PI? (But see below also.) >(Note that the currently-defined XML PI fits this pattern not the one you >suggest.) The authority should come from the public identifier on the >notation declaration for name. Since XML reserves all names beginning with >XML-, I would think that an XML-defined PI should look like: > ><?XML-stylesheet type="text/dsssl" href="foo.dsl"?> This is a good point. In that case, then the XML PI at the top should start with "<?XML-prolog" or something. I don't care which way it goes, but it should be consistent to the extent possible. Also, I'd like to be able to describe the PI "template" and any intended constraints on the values by showing a mock ELEMENT/ATTLIST declaration, and if it's always <?XML att="value" att="value">, then you can't easily distinguish among the PIs by type.
