If more elements were to be added as children of E, the exponential combinations would make maintenance of content models untenable - it's
reasonable then to conclude that this is not an appropriate approach from the outset. I would use something like:
<!ELEMENT E (A | B | C | X)*>
and use a schema or XSL to advise when elements are found to behave in a way contrary to your intentions but not expressed by the content model.
BTW, this question is probably more suited to 'General discussion of Extensible Markup Language <XML-L@l...>'.
