Description

In https://saxonica.plan.io/boards/5/topics/8129?pn=1, Martin Honnen writes:

In https://www.saxonica.com/saxon-js/documentation/index.html#!conformance/regex I find the statement:

Saxon-JS allows the flags argument to be suffixed with the string ";j". If this option is present then the JavaScript regular expression engine is used directly, which means that the JavaScript rules rather than the XPath rules apply

However I get an error trying to use ;j as a flag. What seems to not raise an error is simply the suffix j as in e.g. analyze-string(., '\bcan\b', 'ij')/fn:match => count().

Is the documentation wrong or the implementation not doing what the documentation says?
