Re: <!ELEMENT C (A,A)> allowed?

Adreas:

	Yes, it is allowed.  This is really the only way in a
DTD to control the exact number of subordinate elements.  The
following would also be correct:

<!ELEMENT C (A, A, A+)>

	This would ensure that you had to have 3 A's but you
could have more.

	Hope this helps.
