* Implements the User-Defined Layer element of an SLD implementation specification
|
62 |
* (version 1.0.0).<p>
|
63 |
*
|
64 |
* In addition to using named layers, it is also useful to be able to define custom
|
65 |
* user-defined layers for rendering.<p>
|
66 |
* Since a layer is defined as a collection of potentially mixed-type features, the
|
67 |
* UserLayer element must provide the means to identify the features to be used. All
|
68 |
* features to be rendered are assumed to be fetched from a Web Feature Server (WFS) or a
|
69 |
* Web Coverage Service (WCS, in which case the term �features� is used loosely).
|
70 |
*
|
71 |
* The remote server to be used is identified by RemoteOWS (OGC Web Service) element.
