Process all elements in the list of relativePaths referring to elementXref to get the elementNames corresponding to the extensions encountered. When the entries are processed and it's determined that the document has been dirtied, then the new xml is written back to the adfmXmlUrl.

Parameters:

relativePaths - The paths to ensure added in the metadata directory

removalPaths - The paths to remove from the metadata directory. The assumption is that only one type will be responsible for a path at any given time. So it can be removed without reference to the type.

elementXref - The extension to elementName cross reference for constituent files of the metadata registry, null assumes adfm entries.

adfmXmlUrl - The output file to update if needed

remaining - pass a non-null and the [0] element will contain how many remain in the doc when method completes (from a wildcard)

Returns:

Whether the document has been dirtied by the processing
