In article <COL119-W34A7452319DE17FB85BC62F1A40@p...> you write:

That doesn't make sense.  How can it be required and have a default?

Why not?  It's equivalent to <element-name attribute-name="en3"/>.
If you want the user to have to specify the attribute, mark it
required:

<!ATTLIST element-name attribute-name (en1|en2|en3) #REQUIRED>

It seems you want to have the attribute be required, but have an
editor default to a particular value.  XML doesn't have any way to
specify that kind of interaction with editors.  By "default value",
XML means one that's used when the user doesn't specify one, not one
that is inserted by an editor.
