The <xslt> element

The xslt element of the configuration file contains properties specific to XSLT. Remember that these are defaults, they can always be overridden for specific queries or transformations. An attribute whose value is set to a zero-length string is ignored, the effect is the same as omitting the attribute.

Attribute	Values	Effect
initialMode	A mode name (QName)	The name of a mode within a stylesheet in which execution should begin.
initialTemplate	A template name (QName)	The name of a named template within a stylesheet where execution should begin.
messageEmitter	Java class that implements `net.sf.saxon.event.Receiver`	Destination of `xsl:message` output.
outputUriResolver	Java class that implements the Saxon `OutputURIResolver` interface	Handles documents written using `xsl:result-document`.
recoveryPolicy	recoverWithWarnings\|recoverSilently\|doNotRecover	Indicates how XSLT recoverable errors are handled (for example, ambiguous template rules).
schemaAware	true\|false	Indicates whether stylesheet should be compiled to be able to handle schema-typed input, even if they contain no `xsl:import-schema` declaration.
staticErrorListener	Java class that implements the JAXP `ErrorListener` interface	Receives reports of compile-time errors in a stylesheet.
staticUriResolver	Java class that implements the JAXP `URIResolver` interface	User-defined class for dereferencing URIs on `xsl:include` or `xsl:import`.
styleParser	Java class that implements `XMLReader`	XML parser used for stylesheet and schema modules.
version	0.0, 2.0, or 3.0	XSLT language version to be supported by the processor. The value 0.0 indicates that the version is taken from the `xsl:stylesheet` element.
versionWarning	true\|false	False suppresses the warning produced when the XSLT processor version is not the same as the version in the `xsl:stylesheet` element.

The xslt element may contain one or more extensionElement children defining namespaces used for extension instructions. The extensionElement element has the following attributes:

Attribute	Values	Effect
namespace	A namespace URI	The namespace URI of the extension instructions.
factory	The name of Java class that implements the Saxon interface `ExtensionElementFactory`	Links to the implementation of the various extension instructions in the specified namespace.
