Is the information given in the documentation at http://saxonica.com/html/documentation/sourcedocs/streaming/streaming-extensions-and-restrictions.html about match="para[1]" correct?

http://saxonica.com/html/documentation/sourcedocs/streaming/streaming-extensions-and-restrictions.html says

Streaming extensions are enabled only if requested using the configuration option FeatureKeys.STREAMABILITY. The following extensions are offered:

[...] Saxon retains a count of the number of preceding siblings (by node name) of streamed elements, both for the currently processed element and for its ancestors. This information allows match patterns such as @match="para[1]"@ to be used in streamable template rules.

however when I try to run a stylesheet having

using @Saxon-EE 9.7.0.18J@ from the command line with the option @--streamability:extended@ I get an error

Static error at xsl:template on line 10 column 33 of test2017060504.xsl: XTSE3430: Template rule is declared streamable but it does not satisfy the streamability rules.

  • The match pattern is not motionless

Is that documentation outdated or do I need a different configuration option to enable that streaming extension and support of @match="item[1]"@?

Thanks for pointing this out. This statement should have been dropped in 9.7. Saxon 9.6 attempted to do this (I don't really know how successfully) but 9.7 has attempted to bring the streaming rules into line with the W3C spec.
