I am trying to add some external features to BaseX, and would like to use them into a BaseX client XQUERY module. I can't see any simple way to do it, is there any ?

Here is the scenario : suppose that you want to add a super-mega map module to BaseX, let us call it supermegamap, that is a collection of functions : supermegamap:new, supermegamap:contains, supermegamap:get.

I would like to use my supermegamap through BaseX via a xquery module : 

let $my_supermegamp := supermegamap:new().

I see only two quite not very handy ways to do this :

1) The first one is to use JAVA bindings. Ok, it will work, but is not really elegant.

2) The second one is to fork BaseX code : adding the JAVA code to BaseX, modifying the file Function.JAVA. That might work, should be efficient, but it is quite heavy, and overall, will be most probably a dead-code the next time I will have to upgrade BaseX.

Is there any alternative way ?

Thx
