Attributes

id?
id
Used to reference stylesheet modules embedded in a document.
version
decimal
Standard attribute that may appear on any XSLT element. Indicates the version of XSLT required by the stylesheet.
To request XLST 3.0 processing (which requires Saxon-PE or Saxon-EE), setting version="3.0" on the xsl:stylesheet element is recommended, but is not sufficient on its own. An explicit request must be made on the command line or by the API. Using the XSLT 3.0 processor, a value greater than 3.0 invokes forwards compatibility mode.
When using the XSLT 2.0 processor (in particular, using Saxon-HE), a value greater than 2.0 invokes forwards compatibility mode.
default-mode?
eqname | "#unnamed"
Standard attribute that may appear on any XSLT element. Defines the default value for the mode attribute of all xsl:template and xsl:apply-templates elements within its scope.
default-validation?
"preserve" | "strip"
Standard attribute that may appear on any XSLT element. Defines the default value for the validation attribute of all relevant instructions appearing within its scope. The default is strip.
input-type-annotations?
"preserve" | "strip" | "unspecified"
Used to request stripping of type annotations. The default is unspecified.
default-collation?
uris
Standard attribute that may appear on any XSLT element. Specifies the default collation used by all XPath expressions appearing in attributes or text value templates within its scope (unless overridden by another default-collation attribute on a descendant); and used by certain XSLT constructs within its scope. If present it must be a whitespace-separated list of collation URIs, that use the scheme and path http://www.w3.org/2013/collation/UCA (to request use of the Unicode Collation Algorithm), or collations otherwise recognized by Saxon (see Collation).
extension-element-prefixes?
prefixes
Standard attribute that may appear on any XSLT element. Used to declare the use of extension instructions in a particular namespace.
exclude-result-prefixes?
prefixes
Standard attribute that may appear on any XSLT element. Used to designate namespaces as excluded.
expand-text?
boolean
Standard attribute that may appear on any XSLT element. New in XSLT 3.0, and Saxon 9.5. If set to yes, enables the use of text value templates - expressions enclosed in curly braces within text nodes, behaving the same way as attribute value templates in attribute nodes - for descendant text nodes (unless overridden by another expand-text attribute on a descendant). The default is no.
use-when?
expression
Standard attribute that may appear on any XSLT element. Used to conditionally include or exclude elements. The value is an XPath expression that can be evaluated statically. If the effective boolean value is false, then the element and all its descendants are effectively excluded from the stylesheet module.
xpath-default-namespace?
uri
Standard attribute that may appear on any XSLT element. Determines the namespace used for any unprefixed element name or type name within an XPath expression. The value may be overridden by another xpath-default-namespace attribute on a descendant. The default is a zero-length string, for names in no namespace.
saxon:explain?
boolean
Saxon attribute that may appear on any XSLT element. If the value is yes, then at compile time Saxon outputs (to the standard error output) a representation of the optimized expression tree for the template or function containing that instruction.
