(or whatever is best reference for DER).

The link you gave is to the 2002 revision.
http://www.itu.int/rec/T-REC-X.690-200811-I/en has the latest revision
(Nov. 2008) and, AFAIK, is the most visible link to people searching
for X.690.

That said, X.690 is the definitive DER document (if not exactly the
easiest read). A link to it wouldn't hurt.

These all look good to me.
