No, that's a validity error unless the something-else is malformed.

For example, if the DTD says element type A can only contain an 
instance of element type B, and your file has

   <A><B>text</B><C>text</C></A>

then that is a validity error. It's well-formed, but it conflicts
with the DTD.

If, on the other hand, it said <A><B>text</B><C>text<C></A> then
that is not well-formed, and it's an error regardless of whether
you use a DTD or not.
