Review Comment:
Looking at Scala XML for inspiration, this this their logic to convert
pretty print to CDATA:
https://github.com/scala/scala-xml/blob/main/shared/src/main/scala/scala/xml/PCData.scala#L23-L34
So essentially they just have a special case to deal with strings that
contain the CDATA closing characters (i.e. `]]>`), and everything else is just
output exactly as is. Isn't that what we want to do or is it more complicated
than that?
