An outline proposal

Although I'm not interested in the standardization of some sort of full Zip
(mostly because of all the platform-specific variations), I think this is an
useful perspective.

Do we know why the proposal of a Zip-Lite failed?  Are there comments on the
NWI ballot that we should be examining?  I say that because it might be the
other aspects of making provisions for content that facilitate document
packaging that might have been an issue?  And it just might have been that
the value of a Zip lite scope was not well-understood.

But if we want to do something useful then I see at least three paths:

1) Standardize the entire functionality described in the current ZIP 
Application Note.  But use this standardization process to receive formal 
patent disclosures which should clarify which parts of the specification 
require patents, and whether those patents are available on RAND terms. 
The existence of patents is not a formal bar against standardization in 
ISO/IEC, so long as they are disclosed and are available on RAND terms.

2) Standardize a subset of the ZIP Application Note that is believed to 
involve only royalty-free methods and which is sufficient for document 
format use.  Note that this is close to the proposal that recently failed 
to receive sufficient support in SC34.  So I suggest we need to go beyond 

3) Do #1 and then do #2 as a profile standard of #1.  In other words, if 
we do #1 in a modular fashion, then #2 easily falls out of it.  I prefer 
this approach. It gives everything that supporters of the original 
proposal wanted (ZIP-lite) as well as standardizing the other parts of 
ZIP, which are very important and market-relevant.  The key is 
modularization, which facilitates profiling.
