Xslt3

Defines when and how an xsl:accumulator's value is updated, matching nodes by pattern and firing at the start or end of matched elements.

Creates an XDM array from xsl:array-member children, providing ordered positional access to sequences of arbitrary XDM values in XSLT 3.0.

Defines a single member inside an xsl:array; the member value is any XDM sequence, including nested arrays, maps, or empty sequences.

Exits an xsl:iterate loop early and returns an optional final value, enabling efficient early-termination patterns over large sequences.

Handles dynamic errors thrown inside an xsl:try block, with access to error code, description, and value for precise recovery logic.

Processes a streamed sequence in multiple independent branches simultaneously, enabling multiple aggregations in a single pass over a large document.

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.

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