File type specification:
The SGML file extension is associated with the Encoded Archival Description Document file format.
Encoded Archival Description is an XML standard for encoding archival finding aids, maintained by the Library of Congress in partnership with the Society of American Archivists.
It conforms to all SGML/XML (ISO 8879) specifications. It has been thoroughly tested using a wide variety of existing SGML/XML software. To be used as an XML DTD, "switches" have been included in the DTD for turning off features used only in SGML applications, and turning on features used in XML applications.
