l.opengeospatial.org/files/?artifact_id=1188"> OGC Styled-Layer Descriptor Report (OGC 02-070) version 1.0.0.:
```
 <xsd:element name="Fill"> <xsd:annotation> <xsd:documentation> A "Fill" specifies the pattern for filling an area geometry. The allowed CssParameters are: "fill" (color) and "fill-opacity". </xsd:documentation> </xsd:annotation> <xsd:complexType> <xsd:sequence> <xsd:element ref="sld:GraphicFill" minOccurs="0"/> <xsd:element ref="sld:CssParameter" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType> </xsd:element> 
```
Renderers can use this information when displaying styled features, though it must be remembered that not all renderers will be able to fully represent strokes as set out by this interface. For example, opacity may not be supported.

Notes:
- The graphical parameters and their values are derived from SVG/CSS2 standards with names and semantics which are as close as possible.
