As I recall, you might want to recover the contents as nodes. 

If that is the case, don't do something that converts it to a string,
whether the string contents of the processing instruction or the string
contents of a comment.

*Something* will happen in there, some of the time, as the content is
exposed to editors.  A cut-and-paste operation will go awry, someone
will make a note to themselves, something.  And since it's just a
string, there won't be any kind of automated checking.

And then you will try to unwind it back into markup and something
inexplicable and awful will happen to that process, and you'll have to
find it and fix it, over and over again.

Ken's "sacrificial foreign namespace" solution really is much less work
in the long run.
