Constraints on Attvalues

In my ongoing struggle to master the XML 1.0 spec can anyone help me
with the following:
Concerning production [41] in sect 3.1 there is a well-formedness
constraint which says that the Attvalue cannot contain any direct or
indirect references to an external entity.
So for my element:
<myelem attrib="&ent;"/>

&ent; can only refer to an internally declared entity, and the literal
in the entity value, EntValue, cannot contain
"....&Another_ent;...."
where &Another_ent; is an external general entity.

Am I on the right lines?
