Document Type Description (DTD)

A Document Type Definition (DTD) is a collection of XML markup declarations that, as a collection, defines the legal structure, elements and attributes that are available for use in a document that complies to the DTD.

When loading an XML file, TX Text Control ActiveX Server automatically looks for the corresponding DTD on the local file system, from a network path or over the Internet.

Once the XML file is loaded, TX Text Control ActiveX Server is able to prevent end-user from applying changes that would invalidate the XML contents using the associated DTD.
