Summary0004866: BNF ValueOrAttribList rule does not allow single-element lists
DescriptionValueOrAttribList rule does not allow single-element lists, which results in broken compatibility with the ETSI IPv6 test suites, because of a change in the Complement rule:

("+" denotes added rules, "-" denotes removed / substituted rules):

(+)Complement ::= ComplementKeyword ValueOrAttribList
(-)Complement ::= ComplementKeyword ValueList
...
ValueList ::= "(" ConstantExpression { "," ConstantExpression } ")"
ValueOrAttribList ::= "(" TemplateBody { "," TemplateBody }+ ")"

The problem is the "+" modifier in the ValueOrAttribList. The change to the Complement rule was introduced in v3.3.2 (with a misspelling of ValueOrAttribList as ValueOrAttribListValueList) and then corrected in v3.4.1. However the ValueOrAttribList rule itself has not been changed.

This can be resolved by defining

Complement ::= ComplementKeyword "(" TemplateBody {"," TemplateBody} ")"

(ValueOrAttribList is needed as is for value list matching)
