XSLT 2.0 implementation
This version introduces initial support of features defined in working drafts of XSLT 2.0 and XPath 2.0.
Version 7.0 should be regarded as an experimental alpha release. For production use, please continue to use Saxon 6.5
The Saxon package name has changed from com.icl.saxon to net.sf.saxon.
Any applications that use Saxon java classes directly (rather than relying on the JAXP
interface) will need to be modified. Note that this also affects the settings of the system
The entry point from the command line has changed from com.icl.saxon.StyleSheet to net.sf.saxon.Transform.
The namespace URI for saxon extensions has changed from http://icl.com/saxon to http://saxon.sf.net/. Note that many extensions have been withdrawn, as they are superseded by facilities in XPath 2.0 and/or XSLT 2.0.
To allow coexistence, the name of the JAR file for this release has changed to
saxon7.jar. The SQL extensions are now in a separate JAR file,
A transformation can now be executed directly from the JAR file using the command
java -jar saxon7.jar in place of
Saxon now requires JDK 1.2 or later to run. In consequence, Saxon will no longer work with the Microsoft Java VM, and the Instant Saxon version of the product is therefore no longer available.
Because Saxon no longer runs with the Java VM, it can now be run as an applet within Internet Explorer only if the Sun Java plug-in is installed. You can get this from http://java.sun.com/getjava. This may require some configuration changes because of the differences in security policy.
The following sections summarize the main new features. These assume familiarity with the XPath 2.0 and XSLT 2.0 specifications; however, summaries of the new syntax for expressions and XSLT elements are included in this package.
xsl:value-of element has a new
separator attribute, so it can
be used to output a sequence.
xsl:for-each element supports arbitrary sequences.
The extension elements
xsl:for-each-group instruction, and the associated
function, are implemented.
xsl:result elements are implemented;
Note that the XSLT 2.0 specification is more restrictive as to what can appear in a function
body: it has to be zero or more
xsl:param elements, followed by zero or more
xsl:variable elements, followed by an
However, this is not a serious restriction in practice, because most computations can now
be carried out within a single XPath expression.
xsl:namespace instruction is implemented (it writes a
namespace node to the result tree)
xsl:copy-of can now handle sequences containing simple-values
(the simple value is converted to a string and written to the result tree).
separator attribute is not yet implemented.
xsl:documentelement (and its synonym
saxon:output) are replaced by
xsl:result-document. This no longer includes the serialization attributes directly, instead it refers by name to an
xsl:outputdeclaration, or can use the unnamed
xsl:outputdeclaration by default.
xsl:output element now supports
method="saxon:xhtml". The precise details of the output may not be fully
conformant with the specification.
xsl:destination element is provided, however, since the
attribute is currently ignored, it is not very useful at this stage.
saxon:handler element is no longer supported.
xsl:script element is no longer supported - however,
saxon:script remains available
collation attribute has been added to
and the implementation of sorting now uses JDK 1.2 collators. The
attribute must match the name attribute of a
If none is specified, the
lang attribute is now used to select a collator, or if the
lang attribute is omitted, a collator is obtained for the default locale.
Named sort keys are available, via the
xsl:sort-key element. A named
sort key may be used to perform a sort from within an XPath expression, using the new
