I prefer PIs. I don't like the idea that the currrent mechanism to insert script also carries
an implied structural significance - that  might sometimes be true, but I'd prefer to be able
to make that decision. Also, I think that script is very much a "processing instruction" type
of thing. Would we then require/desire more control over PIs by allowing them to support
attributes though? If you had to wrap the PI in an element just so you had somewhere to store
other information it would seem not to buy much, but it would be interesting if the PI was
able to handle them as well. Even without attributes I prefer PIs - they seem more natural
than an element and a CDATA section.
