# Named Entity Recognition Grammar Syntax

The tables in this section describe the Named Entity Recognition grammar syntax defined in the `edk.dtd` (see Named Entity Recognition Grammar DTD).

In these tables, the terms in angled brackets <> describe the value that you must insert. The XML elements, attributes, and values are defined in lower case.

Although the Named Entity Recognition compiler accepts uppercase element and attribute names, this functionality is deprecated, retained for backward compatibility.

The `edk.dtd` file represents the current definition for Named Entity Recognition grammar files. All Named Entity Recognition grammars must follow this DTD.
