         Let me start by thanking Boudewijn for putting this together 
as a starting point for discussion...and I'll also be glad to start 
the ball rolling with a few comments.  These are not in any particular order.

* Metadata should be stored as XMP.  It's XML-based and the current 
industry standard for metadata in images & compound documents.

* All binary data should be stored as a separate file in the archive 
and referenced from an XML "manifest".  There should be NO Base64 
encoded data in any XML.

* Any hierarchical arrangements should be described in XML and not 
using the "fake directories" of ZIP/Tar. However, common naming 
conventions for files/paths should be established.

* Image data should be stored in either PNG or "raw bits" - lossless 
formats that are easy to access.  PNG should be used for any data 
that which is compatible with it, and "raw bits" for anything that is 
not (eg. CMYK or Lab data, floating point, etc.)

* I would use SVG Tiny/Basic for handling both Paths and Text.  I 
think supporting the full ODF grammar for text layers is simply 
overkill for this - and will tend to keep many implementers 
away.  SVG 1.1/1.2 provide, IMO, all the text and path features you 
should need.
