Used within an xsl:choose element to indicate the default action to be taken if none of the other choices matches.

Content: sequence-constructor
Permitted parent elements: xsl:choose
Element has no attributes

Notes on the Saxon implementation

Provided that syntax extensions are enabled, Saxon (from 10) allows the xsl:when and xsl:otherwise elements to return a value using a select attribute in place of a contained sequence constructor.
