/**
|
54 |
* Implements the ExternalGraphic element of an SLD implementation specification
|
55 |
* (version 1.0.0).<p>
|
56 |
* The ExternalGraphic element allows a reference to be made to an external graphic
|
57 |
* file with a Web URL. The onlineResource sub-element gives the URL and the format
|
58 |
* sub-element identifies the expected document MIME type of a succesful fetch. Knowing
|
59 |
* the MIME type in advance allows the styler to select the best-supported format
|
60 |
* from the list of URLs with the equivalent content. Users should avoid referencing
|
61 |
* external graphics that may change at arbitrary times. Graphic should be static
|
62 |
* when al all possible.
