This is true.
But it's my opinion that the XML decl is *not* a PI, for three reasons:
- it doesn't match production  because the target is 'xml'
- it doesn't match sections  and , which says that a PI
can only occur in the space starting *after* the XML declaration
- section 2.6 says "Processing instructions (PIs) allow documents to
contain instructions for applications. ". The XML decl contains
instructions for the XML processor which is carefully distinguished
from an application
But I think the spec probably should have had an explicit statement
saying that the XML decl either is or isn't a PI, because it admittedly
kind of walks, swims, and quacks like one. -Tim
