> Is it common practice to structure the content of PIs as attribute/value pairs? It wasn't in the old days, XML started a trend I think with pseudo attributes in the xml declaration like encoding="utf8" and xml-stylesheet carried on the tradition. In many original uses the PI is used a a hole in to which to drop processing instructions in the language used by the processor, so often in some completely different non-Tex typesetting language. (In xmltex for example you can drop bits of TeX syntax into a PI and they fall through into the generated document. Basically PI's are a distinguished form of comment, just using <? ?> instead of <!-- -->.
