Re: [Exist-development] [exist:code] dizzzz committed to eXist-db Code: [ignore] introduction of function namespace "http://www.w3.org/2005/xpath-functions/math" of xquery3/xpath3 (see http://www.w3.org/TR/xpath-functions-30/#trigonometry). Basically it is a copy/stripdown from the already existing eXist-db math extension I wrote ages ago; the latter will be stripped so there will be no functions doubled. WorkInProgress.

You dont need to change the prefix. The prefix is opaque, its the namespace
that matters. That said it doesnt matter if you change the prefix because
it is opaque.

I think we must.

Sure, bring the math module into the core code-base rather than as external
and then abstract the core code into business logic classes and call from
both function wrappers. Or only move the now W3C common code into the core,
abstract it still and then have the math module call it.
