Vector Behavior Example (Fixed/HTTP/GML)
Vector layer with a Fixed strategy, HTTP protocol, and GML format.
The vector layer shown uses the Fixed strategy, the HTTP protocol,
and the GML format.
The Fixed strategy is a simple strategy that fetches features once
and never re-requests new data.
The HTTP protocol makes requests using HTTP verbs. It should be
constructed with a url that corresponds to a collection of features
(a resource on some server).
The GML format is used to serialize features.
