Re: [Geopriv] HELD Context & Common Policy

It seems a little odd to put the "snapshot" designation in the 
"transformations" field.  I think of the transformations as modifying 
whatever LO the LS started with, whereas, the snapshot flag tells the LS 
what LO to start with.

Would it be appropriate to use the "actions" stanza to describe what 
location the LS should use as a base, namely snapshot vs. current?

<actions>
   <co:determine-snapshot time="2008-07-124T8:00:00+01:00"/>
</actions>

<actions>
   <co:determine-current />
</actions>
