Defines a named decimal format controlling how format-number() formats numbers in XSLT 1.0 and later.

Controls the visibility of components in an xsl:package, determining which are accessible to consuming packages.

Defines a named index for efficiently selecting nodes using the key() function in XSLT 1.0 and later.

Emits a diagnostic message to the processor's error output; optionally terminates transformation with terminate='yes'.

Maps a namespace prefix used in the stylesheet to a different prefix in the result tree, enabling stylesheets that generate XSLT.

Formats a number or automatically generates a sequence number based on the node's position in the document.

Inside xsl:use-package, provides local implementations that replace specific components imported from the used package.

The root element of an XSLT 3.0 package, a named and versioned reusable unit of stylesheet components.

Declares which accumulators are active for a streaming template or mode, enabling the processor to compute only necessary values.

Declares that the current stylesheet or package uses components from a named external XSLT 3.0 package.
