The use of XML documents in systems configuration is widespread. XML documents represent data that is complex and can be structured in various ways. The XML based editing offers a powerful environment for editing hierarchical and structured XML datasets.

XML editing promises are made in a edit_xml, which is then used in the edit_xml attribute of a files promise. The promiser of the files promise needs to be the XML document that is being edited. Within an edit_xml bundle, various promise types are available to create new or manipulate existing XML documents.
