Saxon-JS Release Notes
Maintenance release 1.1.0
9 May 2018
Bug fixing maintenance release.
In general for use with Saxon-JS 1.x SEFs should be produced with Saxon-EE 188.8.131.52
later, though to be able to use all new features of Saxon-JS 1.1 it is recommended
SEFs are produced with Saxon-EE 184.108.40.206 or later (beware the
ixsl:schedule-action/@wait bug #3734 in 220.127.116.11 and 18.104.22.168).
See the Change History
section of the documentation for full details. Below is a summary:
Type Conversion and Supplying
stylesheet parameters for up to date details.
Serialization to JSON is implemented (with some restrictions).
Added two ways to set the logging level for warnings, processing messages, or full
tracing, using the Saxon-JS API: the API method SaxonJS.setLogLevel,
and the SaxonJS.transform
Additions to the SaxonJS.transform
tunnelParams to allow
parameters to be supplied for call-template invocation.
The extension instruction ixsl:schedule-action
has been updated to allow document fetches and HTTP requests to be terminated:
either using a timeout, or by user initiated abort. Requires Saxon-EE 22.214.171.124
or later at compile time. See HTTP
request termination for more information and examples.
Some Saxon extension functions are now available in Saxon-JS (see Saxon

Maintenance release 1.0.2
5 October 2017
Bug fixing maintenance release.
In general for use with Saxon-JS 1.0 SEFs should be produced with Saxon-EE 126.96.36.199
later, though a number of features introduced in Saxon-JS 1.0.1 require SEFs produced
with Saxon-EE 9.8 (see the documentation for details).
- A space-separated list can now be supplied in the
document attribute of
ixsl:schedule-action, to fetch
multiple documents before the contained call is invoked.

Also includes a patch for a known Edge bug related to regular expressions used in
resources (see Forum issue #6873).
Maintenance release 1.0.1
21 July 2017
Maintenance release for use on web browsers. A number of new features require SEFs
produced with Saxon-EE 9.8 (in general SEFs should be produced with Saxon-EE 188.8.131.52
later for use with Saxon-JS 1.0).
- Many more XSLT 3.0 features are now implemented. Some require Saxon 9.8 at compile
for full details. Newly implemented features include:
xsl:where-populated, xsl:on-empty, xsl:on-non-empty, xsl:fork
- use of initial mode
- accumulators (requires Saxon 9.8)
collection() (requires Saxon 9.8)
- merging (requires Saxon 9.8)
- multiple packages (requires Saxon 9.8)
xsl:source-document in non-streaming mode (requires Saxon 9.8)
xsl:context-item (requires Saxon 9.8)
- Support for collations has been extended to XSLT instructions as well as XPath
- Regex character class subtraction
- Fixes for
xsl:evaluate (default XPath namespace; support for
@as result type restriction; support for
in addition to
- Additions to the
function-params to allow function call
collations to supply collations;
to supply collections.
initial-mode set to
"#unnamed" can be used to force use of the unnamed mode. If
is not set, then the default-mode specified in
xsl:package) is used, defaulting to the unnamed mode.
- Added interactive XSLT mechanism for making asynchronous HTTP requests directly from
stylesheet - using the new
http-request attribute on
(requires Saxon 9.8). See HTTP
messages for more information.
- Using Saxon 1.0.0 or earlier, URIs in the
doc() function and in the
document attribute of
ixsl:schedule-action were always
interpreted relative to the SEF's location. In Saxon-JS 1.0.1, the behaviour depends
whether the SEF is relocatable, since this will determine the
static-base-uri(). From Saxon 9.8, a relocatable SEF can be produced by
setting the Transform command line option
-relocate:on at compile time. If
the SEF is relocatable, then
static-base-uri() is the base URI of the SEF;
otherwise it is the location of the XSLT stylesheet at compile time. For full details
see the section about relative URIs at Source
