To add more context, this relates to the the RESTCONF JSON vs. XML
discussions in the NETCONF WG.

  leaf broken {
      type union {
        type int32;
        type string;
     }
  }

If all values of key leaf "broken" are sent as strings in an
instance-identifier,
then the int32 value may not match in all implementations, instead of the
string.
Allowing numbers as literals in addition to quoted strings allows the sender
to be specific, and all implementations to be consistent.
