Declaring the document type

You must declare the document type before you can convert a source file that contains the tag markup for dialog elements, Do this by coding the DOCTYPE declaration at the beginning of the source file. The DOCTYPE declaration looks like this:

<!doctype dm system>

Where:

<!: Begins the markup declaration
DOCTYPE: Identifies the declaration as a document type declaration
DM: Specifies that the source file contains tags used to define dialog elements for a Dialog Manager application
SYSTEM: Indicates that the syntax rules for defining elements are contained in an external file
>: Closes the markup declaration.

External files that are embedded (through the use of entity declarations) within the source file intended for conversion cannot contain a DOCTYPE declaration. They are converted using the DOCTYPE declaration of the source file they are embedded within. For more information about entity declarations and embedding external files within source files, see Defining entities and parameter entities.
