I don't understand the point of this question.  You can obviously look at
a WF document and construct a DTD that would make it valid, thus:

1) Declare every element type, giving it a content model of the form
((A, B, C, ...) | (D, E, F ...) | ..., in other words, a choice between
sequences, where each sequence represents the actual children that
every element of that type actually has.  Alternatively, give them all
a content model of ANY.

2) Declare every attribute, giving it a type of CDATA and a value of #REQUIRED
(or #IMPLIED, or #FIXED "actual-value", or "actual-value", as you will).
