There is one thing I would like to add to the feedback which I sent recently on the similar location draft:

Section 4 discusses briefly the possibility of the server limiting the number of returned similar locations.  Although the current text expresses the general idea that there may be a few that are the "most likely" to be the correct location, there are also scenarios where many similar locations could all be equally likely, and the server might need to simply cut off the list at a reasonable count.  In those situations, I believe it would be helpful if the server indicated when such  a limit is actually applied.

I suggest that an attribute be added to the locationValidation element of the findService response, perhaps rli:similarLocationsLimited, having a data type of boolean, with instructions that a server SHOULD include this attribute if the number of returned similar locations is limited due to configuration or policy.
