(draft-issue-1 value);
-	reverts values indicated by the Length of Length field to draft-issue-1 
values;

the maximum size of the header to 8 octets from the draft-issue-1 size of 5 
octets.

Substantive changes, confined to pages 4-1 through 4-5, are flagged with 
change bars in the right margin.  Changes proposed in draft issue 2 but not 
adopted have been discarded without markup.
