Yes.

Or write RFCs with ambiguous normative part which cannot be understood
with the non-normative part. :-)

As I said in a previous message,  the pb also occurs in a string form
like   cn=Paul, O=VPN Consortium

I think one might want enhance the normative part of RFC 5280:

    The Name describes a hierarchical name composed of attributes, such
    as country name, and corresponding values, such as US.  The type of
    the component AttributeValue is determined by the AttributeType; in
    general it will be a DirectoryString.

without other texts of X5xx this is also ambiguous. It doesn't say
how the hierarchy is encoded, etc for name constraints, what
is a subtree (prefix or suffix)?  I may have overlooked something?
