Saxon

The EXPath Archive standard reached an intermediate draft state that didn't progress any further in the Spring of 2014. Unfortunately I created anticipatory Saxon documentation which linked to (unimplemented) functions in that draft - specifically the four you mentioned. Until the standard is better defined (and we'll work on it), our implementation won't have them specifically, and we'll drop them from the documentation.

However, these four functions are all convenience rather than fundamental functions, as the draft standard shows, and can all be implemented by compound XPath/XSLT actions, building on other Archive functions and others from EXPath File. For http://expath.org/spec/archive/editor#fn.from.files, http://expath.org/spec/archive/editor#fn.to.files and http://expath.org/spec/archive/editor#fn.xml the draft contains suitable code samples. (If you're in pure XPath you'll need to use let constructs for the intermediates). For http://expath.org/spec/archive/editor#fn.text, unless you anticipate having to process empty sequence arguments, bin:encode-string() will suffice.

As suggested above, the unimplemented functions have now been removed from the documentation (for 9.7 and 9.6 in the archives and online, and also the 9.8 dev branch).
