XForms/Storing Tabs in the Model

Motivation

You want to dynamically modify your tabs while the form is executing.
Method

Rather than statically loading all your tabs in the form body it is also possible to store your tabs in the XForms model and then display each of them by using a repeat.
Full Example

declare namespace h = "http://www.w3.org/1999/xhtml";

let $content-type := "text/xml"
let $mode := xdmp:set-response-content-type($content-type)
let $results := 
(
processing-instruction {'xml-stylesheet'} {'type="text/xsl" href="/lib/xsltforms/xsltforms.xsl"'},
