Sam,
It seems that a set of delimited strings as a way of constraining text
string values is not documented in the latest ADL specification.
"Constraints on String Strings can be constrained in two ways: using a
fixed string, and using a regular expression." -- from ADL Rev 1.3 -
release 0.96.

There is actually support for delimited strings in the java ADL parser,
one can switch it on by swapping the production rules at line 2350,2351
and line 2353,2354.
The result should be something like:
LOOKAHEAD( string_list_value() )
list = string_list_value() [ "," <SYM_LIST_CONTINUE> ]
|
LOOKAHEAD( string_value() )
value = string_value()

Rong
