/**

* Implements the main class for the SLD implementation specification (version 1.0.0)
|
60 |
* which starts the parsing of the styled layer descriptor document in order to store
|
61 |
* all the information that it has inside and transform it into objects.<p>
|
62 |
*
|
63 |
* An SLD document is defined as a sequence of styled layers.<p>
|
64 |
* The version attribute gives the SLD version an SLD document, to facilitate backward
|
65 |
* compatibility with static documents stored in various different versions of an SLD
|
66 |
* spec.<p>
|
67 |
*
|
68 |
* The Styled layers can correspond to either named layers or user-defined layers,
|
69 |
* which are described in subsequent sections. There may be any number of either type
|
70 |
* of styled layer, including zero, mixed in any order.
