Description:
Raised by Jeremy Carroll in [1]:

12) 9.6.2 well formed lists (slightly substantive, change suggested but not
required)

You could invoke:
http://www.w3.org/TR/rdf-mt/#collections penultimate para
[[
Semantic extensions MAY place extra syntactic well-formedness restrictions on
the use of this vocabulary in order to rule out such graphs. They MAY exclude
interpretations of the collection vocabulary which violate the convention that
the subject of a 'linked' collection of two-triple items of the form described
above, ending with an item ending with rdf:nil, denotes a totally ordered
sequence whose members are the denotations of the rdf:first values of the items,
in the order got by tracing the rdf:rest properties from the subject to rdf:nil.
This permits sequences which contain other sequences.
]]

which I think would be cleaner.
Since condition S35 requires special processing of RDF collections, this is not
imposing much extra burden on implementators. (In fact it is making it easier:
S35 is particularly irksome in the face of forked lists).

2008-11-10: RESOLUTION: We propose to make an editorial change to section 9.6.2., adding the following below example 46: """ However, as stated in [RDF-SEMANTICS] section 3.3.3, semantic extensions to RDF may place extra syntactic well-formedness restrictions on the use of the RDF collection vocabulary (rdf:first, rdf:rest, rdf:nil) in order to rule out such graphs. """
