[Chameleon] Locate Widget

[Paul Spencer]

Ken, I don't know how the NTS MapSheet lookup service is implemented. 
We just connect to the service, provide input in a certain format and 
expect results back in another format.  I would expect that the naming 
convention of mapsheets is sufficient for them to locate the mapsheet 
geographically.  To Chameleon, it is immaterial how you implement the 
service but very important that you clearly define how data is passed to 
and from your service. Hope that helps,

Paul
