Ummm, it's not refereing to _named_ entities but to _numeric_ ones,
are these also expanded?

  SGML and XML both permit references to characters by using
  hexadecimal values. In SGML these references could be made using
  either &#Xnn; or &#xnn;. In XML documents, you must use the
  lower-case version (i.e. &#xnn;)

  http://www.w3.org/TR/xhtml1/#h-4.12

In HTML it is OK to have uppercase numeric entities and XHTML it is
not.

Fair enough, as long as this also happens whe Petal is doing HTML
since you can't use ' in HTML.
