No. The included features are specified by the Web Feature Service standard: only those features matching a filter query are encoded, and nested properties are encoded inside those features or by reference. While it is possible to include additional types at the top level, they will not be related to features of another type. Client applications should be able to use the xlink:href obtained from a response to make a second query to resolve a nested feature. > I've read that it's impossible to ask for a feature referenced by an > xlink:href, then we can't ask the service for the addresses of a certain > thoroughfarename, can we?

Are you talking about a filter query on xlink:href? This is possible where it is created using feature chaining and you are querying a nested property (users like this but I am not sure that it is valid use of WFS!). I am not sure this is what you mean. Do you have an example? Kind regards, Ben.
