XML syntax and examples
CDATA is "character data" and PCDATA is "parsed character data". [? Where did I borrow these examples from? Double check for correctness. Actually, this isn't even complete. ?] Note: Mozilla incorrectly strips <! and > angle brackets when in XMP block.
<![CDATA[
Default:
<?xml version="1.0" standalone="no" encoding="UTF-8"?>
Well-formed:
<?xml version="1.0" standalone="yes"?>
Valid:
<?xml version="1.0" standalone="no"?>

3. XML document with inlined DTD defining attribute lists for its elements.
