Also the content of on-error is used without any checks, so it is 
possible for badly coded templates to generate invalid XML like so:

  <span petal:on-error="&lt;">$fail/me</span>

Unless someone else fancies tackling this, a full fix will have to 
wait.

So I've put a note in the pod documentation that the implementation 
of on-error is incomplete, and added code to defang XML 
metacharacters in the output.
