[oXygen-user] html validation error

Often when I copy and paste HTML code from somewhere, and edit the
resulting page in Oxygen, I get a validation error in

For example, when the DOCTYPE at the beginning says
I get the validation error:
  F [Xerces] The declaration for the entity "ContentType" must end with '>'.

If I click on this error message, it takes me not to my html document,
but to http://www.w3.org/TR/html4/strict.dtd, to the following declaration:

<!ENTITY % ContentType "CDATA"
    -- media type, as per [RFC2045]

The middle of those three lines is highlighted.

I could understand if something in my own HTML were invalid; but this
appears to be saying that the standard DTD provided by W3C is not
I'm not a DTD guru, but I would be very surprised if that were the case.

Is this a Xalan bug, then?

This is not a showstopper for me, but it does make it more complicated
for me to do validation on the html I'm writing.
