/**
* Export values in destination metadata.
*
* This method perform 2 things:
* - import the missing values in the current list.
* - re-order the values with the following paradigm:
* - the values defined in the source metadata first (whereever they
* where in the current list).
* - keep the values that only exists in current list with the same order
* but at the end of the list.
*
* To achieve the last point (ordering) we use a trick:
* - reverse the list and add each element of this list at the beginning of
* the current one.
* With reverse, the last element of the source list will
* be the first to be treated. We insert it at the beginning so the last
* element of the source list will appears before all the existing elements.
* Then each elements will be inserted at the beginning too so they will
* appears in the right order.

* @param Docman_Metadata $srcMd Source metadata
