Comment 1 for bug 1733695

Here is a branch implementing this functionality. From the commit message:

Previously, a multi-valued record attribute could only be extracted using one strategy (XPath, tag+subfield, fixed field, etc). For multi-valued attributes, though, there's no reason to restrict this as long as the values from various sources would, after normalization, have the same shape. So now we allow that, and we update the item_lang definition in order to allow searching for records with multiple languages in various boolean ways.
