    The original issue is resolved by going back to basic
    elements and redefining hierarchical_identifier more simply.

    DELETE:

    simple_hierarchical_identifier AND
    escaped_hierarchical_identifier in Syntax 12-7 and A.9.3

    simple_hierarchical_branch AND
    escaped_hierarchical_branch in Syntax 12-7 and A.9.4

    REPLACE hierarchical_identifier in Syntax 12-7 and A.9.3 with the following:

    hierarchical_identifier ::=
      { identifier [ "[" constant_expression "]" ] "." } identifier

    That is, a hierarchical_identifier is composed of an identifier optionally
    preceded by a sequence of zero or more of the following: an identifier, one
    optional constant (integer) index, and a period.

    Each identifier part of an hierarchical_identifier can be either a
    simple_identifier or an escaped_identifier, and there is no need to
    distinguish between simple and escaped hierarchical_identifiers or
    simple and escaped hierarchical_branches.

    This proposal also assumes the changes proposed in issue #257
    and also supercedes the proposal in issue #208.
