In that case you _definitely_ don't mind.

<![CDATA[ <a>b</a>]]>

and

&lt;a>b&lt;a>

are _identical_ as far as XSLT is concerned. The whole reason why an
XSLT system is always allowed to use either form on output is that
when they are parsed by an XML parser they form the same input.

This is false. An XSLT system will use or not use CDATA markup
as it chooses, but as shown above the output in either case will
form the same input after XML parsing, just as an identity transfom
may output an attribute a="b" as a="b" or a='b' which is a different
linearisation, but with an equivalent XML parse tree.
