I was wondering if the following would be possible in a DTD.  Consider:

<!ELEMENT PARENTS   (FATHER?, MOTHER?)>
<!ELEMENT FATHER   (CHILD*)>
<!ELEMENT MOTHER   (CHILD*)>
<!ELEMENT CHILD (SON | DAUGHTER)>      <========= Alternative!
<!ELEMENT SON (#PCDATA)>
<!ELEMENT DAUGHTER (#PCDATA)>

I've seen OR in the context of element attributes, of course, but what about in element definitions?
