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.
