+ * Symbology encoding for styling map data independently of their source.
+ * The classes in this package are derived from
+ * OGC 05-077r4 — <a href="https://www.ogc.org/standard/se/";>Symbology
Encoding</a> Implementation Specification 1.1.0.
+ * That document defines an XML encoding that can be used for styling feature
and coverage data.
+ * The root elements are
+ * {@link org.apache.sis.style.se1.FeatureTypeStyle} and
+ * {@link org.apache.sis.style.se1.CoverageStyle}.
+ * Those classes include different kinds of {@link
org.apache.sis.style.se1.Symbolizer}.
+ *
+ * @todo Add {@code CoverageStyle}. May require a common parent with {@code
FeatureTypeStyle}.
+ *
+ * <h2>Future evolution</h2>
+ * This package defines a XML encoding.
+ * It is not an abstract model for sophisticated styling.
+ * Apache SIS temporarily uses the classes of the XML encoding as a style API,
+ * but a future version may replace this API by a more abstract one.
+ * A good candidate may be ISO 19117:2012 — Portrayal.
+ * As of 2023, various OGC working groups are also working on new style API.
+ * The final form of such API has not yet been settled down.
+ *
+ * <h2>Synchronization</h2>
+ * Classes in this package are not thread-safe.
+ * Synchronization, if desired, must be done by the caller.
