    <xs:documentation>tooltip: Software Package summary: Defines a software distribution and all of its dependent software. description: The software element contains general information about a software resource that is being documented. This field is intended to give information for software tools that are needed to interpret a dataset, software that was written to process a resource, or software as a resource in itself. It is based on eml-resource and Open Software Description (OSD) a W3C submission. There can be multiple implementations within a software package because a physical software package can run on multiple hardware and/or operating systems. See implementation element documentation for a more thorough explanation.</xs:documentation>
