Soren,
thanks for looking at this.
I didn't want to restrict the contents of NameA.
I did want to restrict the contents of "Atype_Name" to any of the values that actually got used for the NameA.

Sorin, thanks for your interest, here's an example where I would want the enumeration for the attribute "Atype_Name" to contain a list of what the user has input for "NameA": <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/20...

I'm an XML newbie! So I appreciate any help you can give me.

I want to know if there's a way to populate an attribute enumeration
from a list - perhaps from a "keyref"? from some other element.

Pierre
