Subject: EDXL common distribution element

Hello Mike,

First, let me say that I have modified the "reply all" list for this 
message to include only those of whom I am aware are active in the OASIS TC 
process since I am also posting this on the EM-TC list and I deleted the 
discussion that lead up to your comments and request.  Also, Sukumar at 
ComCARE is an individual member and that membership does not provide the 
ability for the other ComCARE members to address the list.  However I 
included you guys since you are active in the process.  Please send any 
comments you have through Sukumar.  I did want to be sure your (Mike's) 
comments are presented to the group as you are a TC member.  BTW - DHS is too.

Please find the attached Issues list provided to the EM-TC after the fall 
EDXL Distribution Element demonstrations as you requested.  This is the 
only summary of results that has been posted to the OASIS web site although 
there may be more.  I understand your concern for the magnitude of the 
effort and the TC is diligently working through the issues, some of which 
you have pointed out.  The senderID represented as a URI has been discussed 
and seems to be our consensus although not firmly decided in meeting 
notes.  We are also discussing the need for a hierarchy in structure for 
the enumerated types and are seeking specific input.  The targetArea 
element will certainly be in concert with OGC and our GIS subcommittee is 
working that detail now.  The EM community is in need of getting the 
distribution element moved through quickly as voiced by the DM program.  We 
are making every effort to support that request.

Thank you for your comments and we welcome your input to the process.
