While Access Manager allows you to view and make basic changes to the metadata of a trusted provider, it does not provide an easy way to retrieve and save the XML that was originally imported. Sometimes you may wish to compare the imported XML to the current metadata, or you may wish to make more advanced changes to the XML and then re-import. Whatever your reason, there is a way to retrieve the trusted provider XML in Access Manager.
