For example, from the DTD is seems that a structure in which a table contains a form that itself contains a table is allowed. The question is, is this the intent? The spirit of the specification would tend to indicate that such nesting should not be allowed even though the DTD does not appear to prevent it.

When the spec says in a normative section, that nested tables are not 
allowed, then it is not allowed, whether this can be expressed in a DTD 
or not. In fact it cannot be expresed with DTD syntax. HTML specs e.g. 
also say, that the value of the href attribute must be a URI, which 
cannot be validated using the DTD.
