Upon reflection, this statement is incorrect.  numericString
is a ASN.1 string type...

and hence likely has significant restrictions upon allowed
characters.  "ASN.1 Complete" says 0-9 and space and when
encoded using BER are represented using the corresponding
ASCII characters.

Per "ASN.1 Complete", no.

This statement, however, appears to be correct given the
syntax restricts.

This is an example of why more specific references are needed.

Now it's to go look at my numeric string syntax validation
function... :-)
