What does the feature source xml look like? It seems that feature source xml
is an invalid document.

> 3- store the session ID in a variable
> 4- Check GET parameters
> 5- if records exists depending on the GET parameters, make a new

> 6- Open this MgSiteConnection object with the session ID
> 7- Create a ResourceService by using MgSiteConnection->CreateService
> 8- Open the map by using $map->Open($resourceService, 'MapName') (EDIT: I
