That’s a really good idea Randy, I shall do that.

The other idea I have been toying with is, if the LIS has it, allowing the LIS to return the address of the LoST server in place of the routing information itself. This would allow areas that deploy LoST servers but not forest guide networks, islands if you like, to still have the authoritative server queried directly. This won’t work in all cases, as the draft describes, but it could assist in some environments.

Cheers
James

From my reading, it appears that the extension is to add an empty <requestRoutingInformation> element to a HELD request, and if the server supports it, it includes a <routingInformation> element with all possible values that could be returned.  Is this correct or am I missing something?  If it is correct, why is the <requestRoutingInformation> element empty rather than contain the desired service?  Wouldn't it be simpler to include the specific service of interest (e.g., 'sos'), as in the <service> element from LoST and then the server only needs to look that up and return only that?
