: pre:pre:default-element
: function that suites as default element constructor for the preproseccing conversion.
: It is more or less a copy function, copying the elements name and its node and recurively leeds the conversion to its child-nodes
:
: @param $node the node to be copied
: @param $recursive-function the recursive function as some kind of call back to the main conversion
: @return item()* representing the converted node
:
: @version 1.0 (2018-01-31)
: @note Would be great if $recursive-function would be a real function and not a node-sequence (TO-DO)
