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.

yes :-)

Didn't I add these URLs to the commit messages?

cheers
