Locates a foreign document, that is not compliant with FMV Grund-DTD.
If the document is an SGML document compliant with another DTD, this element should contain a 'lok.entity' pointing to the document.
If the document is not an SGML document, this element should have no content.
The document may or may not be accessable by the user when he attempts to traverse the link. If it is an SGML document, The SGML/HyTime software should be able to resolve the link. If not, the application must be built to handle the result, whether it is an accessable non-SGML document or it is not accessable at all.
For documents that cannot be accessed (for any reason) the application is supposed to handle the result, e.g. a dialog box could be shown containing the information found in attributes 'dok.namn', 'dok.id' and 'annan.info' of this element.
For further explanations, see the HyTime standard (ISO 10744), clause 8.3.2.1.
