% is only an issue within DTDs, not within document instances.

' and " are an issue only in attribute values that are enclosed
in ' and " respectively.

< and & are a problem everywhere.

You can suppress the special meaning of all characters within
document content (not attribute values) by enclosing them
in the special quotation marks "<![CDATA[" and "]]>".  Of course,
the appearance of "]]>" within your data will screw even this up.
