RE: are entities containing markup allowed in attribute values?

Rob,

This Oasis web page has links to several sites you can use to validate and
check the "well-formedness" of your XML...

  Are entities containing mark-up allowed in attribute values?

  For example, is the following document well-formed?

  <?xml version="1.0"?>
  <!DOCTYPE message [
  <!ENTITY greet "<greeting>Hi</greeting>">
  ]>
  <!--Atribute value has an entity reference: &greet; which contains
mark-up! -->
  <message value="&greet;"/>

  If not, can somebody point out where in the XML 1.0 spec this is mandated?

  Many thanks
