EXSLT - Sets covers those extension elements and functions that provide facilities to do with set manipulation.

The extension elements and functions defined within this document are governed by the general rules about extensions to XSLT covered in [14. Extensions] in [XSLT 1.0].

XSLT processors are free to support any number of the extension elements and functions described in this document. However, an XSLT processor must not claim to support EXSLT - Sets unless all the core extensions described within this document are implemented by the processor. An implementation of an extension element or function in an EXSLT namespace must conform to the behaviour described in this document.

Using EXSLT will only make your stylesheet portable amongst the implementations that support EXSLT. Note that there is no requirement for XSLT processors that are compliant to XSLT to support the extensions described within EXSLT.


The namespace for EXSLT - Sets is:


Throughout this document, the prefix set is used to refer to this namespace. Any other prefix can be used within a particular stylesheet (though a prefix must be specified to enable the extension functions to be recognised as extensions).


Core Functions

The following extension functions are considered stable and are core to EXSLT - Sets. Processors that claim support of EXSLT - Sets must support these functions.

Moved set:difference, set:intersection, set:distinct, set:has-same-node, set:leading and set:traling into the core.
