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 Server for ASP.NET (incl. Windows Forms) 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 Server for ASP.NET (incl. Windows Forms) is able to prevent end-user from applying changes that would invalidate the XML contents using the associated DTD.
