The examples are great, though the stipulation is not
formal as there are _only_ two groups ``within dashes''.

A clear an unambiguous stipulation would include
this definition plus your examples:

      Within each group of 4 hexacedimal digits zeros are
      filled to the right, and groups of zeros are filled
      to the left.
      
      Example:
        4A = 004A-0000-0000-0000
        12C-4-32 = 012C-0004-0032-0000

The advantage is that is is formal, and unambiguous
without a doubt. It implicitly defines what a group
is (four hexadecimal digits), if not defined anywhere
in the embedding document.
