Fair enough.

Yes - several of the tables in the Net-SNMP agent are
index (wholly or partially) by string values.

The Net-SNMP tools would recognise:
snmpget ..... XXX-SNMP-MIB::fooValue.123."elementOne"
(though in practise, you'd need to escape the quote characters:
XXX-SNMP-MIB::fooValue.123.\"elementOne\"
to protect them from being swallowed by the shell).
Internally, this would be expanded to the length plus individual
character values:
fooValue.1.10.69.108.101.109.101.110.164.79.110.101
See RFC 2578, section 7.7, clauses (2) and (3) for the details.
