9.2. Grammar. Does not allow for a prefix length itself having a prefixed length, so does not match property description (ie, the change to permit this is draft 045 omitted to update the grammar).

Proposed change to grammar in 9.2:

PrefixLength = SimpleContent | PrefixPrefixLength SimpleContent

PrefixPrefixLength = SimpleContent

This is sufficient to allow the grammar to describe the needed “one more level” of prefix (as required for modeling an ASN.1 format) without allowing recursion.
