 <xsd:element name="TextSymbolizer" substitutionGroup="sld:Symbolizer"> <xsd:annotation> <xsd:documentation> A "TextSymbolizer" is used to render text labels according to various graphical parameters. </xsd:documentation> </xsd:annotation> <xsd:complexType> <xsd:complexContent> <xsd:extension base="sld:SymbolizerType"> <xsd:sequence> <xsd:element ref="sld:Geometry" minOccurs="0"/> <xsd:element ref="sld:Label" minOccurs="0"/> <xsd:element ref="sld:Font" minOccurs="0"/> <xsd:element ref="sld:LabelPlacement" minOccurs="0"/> <xsd:element ref="sld:Halo" minOccurs="0"/> <xsd:element ref="sld:Fill" minOccurs="0"/> </xsd:sequence> </xsd:extension> </xsd:complexContent> </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.
