Generally, I agree that a SCRIPT could (should) be an element.  But some
script languages or even statements require specific formatting.  For
example, a Javascript single-line comment must not wrap; some Python code
depends on specific indenting; etc.  I can imagine that a processor, finding
a PI at that point, would preserve the special formatting where otherwise it
would not.  Of course, the processor could simply know to preserve
formatting when it hits a <SCRIPT> element.

If the processor is XSLT, SCRIPT elements with "<" and "&" characters can be
output properly for HTML (according to the more recent drafts of XSLT), so
here we don't need PIs or CDATA either.
