Because PIs are relatively under-defined (so you can plonk inany old thing you
want) it makes them difficult for DOM or XLL
to say much useful about: if you use an attribute-like syntax
then at least you may have a fighting chance that future common
tools will be able to examine them and use them.
But, of course, piggy-backing PIs onto elements using attributes
is probably always a preferable option, if your PI structure can
matches the start-tag locations.
Even if you use attribute-like syntax, PI values are still just
text strings, from the XML viewpoint. Having a target (notation)
to indicate the syntax of the PI is a great headstart in labelling.
