Reference

Merges another stylesheet's top-level declarations into the current stylesheet at the same import precedence.

Processes a sequence item-by-item with carry-forward parameters, enabling efficient streaming and stateful iteration in XSLT 3.0.

Creates an XDM map from one or more xsl:map-entry children, enabling key-value data structures directly in XSLT 3.0 stylesheets.

Adds a single key-value pair to an xsl:map, where the key is any atomic value and the value is any XDM sequence.

Defines the template body applied to each substring that matches the regex inside xsl:analyze-string.

Merges multiple pre-sorted sequences into a single sorted sequence, processing each group of items with the same merge key via xsl:merge-action.

Defines the body executed for each group of items sharing the same merge key during an xsl:merge operation, with access to the merged items and current key.

Defines the sort key for items in an xsl:merge-source, determining how items from different sources are aligned and interleaved during merging.

Defines one sorted input sequence for xsl:merge, specifying the source data and its merge keys so the merge algorithm can interleave items correctly.

Declares a named mode and its default behaviour when no template matches, enabling modular transformation strategies in XSLT 3.0.
