### 41.1 Understanding DITA2Go content models

A DITA2Go content model is a configuration-style representation of a DTD. A content-model configuration summarizes DTD information in a form DITA2Go can use to produce XML output that conforms to the DTD. DITA2Go provides built-in content models for basic DITA version 1.0 and 1.1 topic types, and for DocBook version 4.5. You do not have to include anything special in your DITA2Go conversion project to use these content models.

The DITA2Go built-in content models were derived from:

http://docs.oasis-open.org/dita/v1.0.1/dtd/ for DITA version 1.0

http://docs.oasis-open.org/dita/v1.1/CS01/dtd/ for DITA version 1.1

http://www.oasis-open.org/docbook/xml/4.5/ for DocBook 4.5.

These content models are complete. You should not need to modify any of them, except possibly to correct element type assignments; see §41.6 Inspecting and correcting element types. Each built-in content model has a matching configuration file.

The DTD for DITA version 1.2 is available here:

http://docs.oasis-open.org/dita/v1.2/cs01/dtd1.2/

You can use utility program dtd2ini to abstract content models from this and other DTDs; see §41.2.2 Generating a content model from a DTD.
