XKMS requirements - initial draft

All,

Here is a first attempt at documenting XML Key Management requirements.  We
attempted to include requirements from a variety of sources, including the
position papers and minutes from the July workshop, the activity proposal
and proposed charter, and comments from the XKMS developer list.

This should provide a good basis for discussion during the conference call
next Thursday.
Comments sent to the list before then would be appreciated as well.
