###########################
Content type constant names
###########################

The following names are defined in the :mod:`opc.constants` module to allow
content types to be referenced using an identifier rather than a literal
value.

The following import statement makes these available in a module::

    from opc.constants import CONTENT_TYPE as CT

A content type may then be referenced as a member of ``CT`` using dotted
notation, for example::

    part.content_type = CT.PML_SLIDE_LAYOUT

The content type names are determined by transforming the trailing text of
the content type string to upper snake case, replacing illegal Python
identifier characters (dash and period) with an underscore, and prefixing one
of these seven namespace abbreviations:

* **DML** -- DrawingML
* **OFC** -- Microsoft Office document
* **OPC** -- Open Packaging Convention
* **PML** -- PresentationML
* **SML** -- SpreadsheetML
* **WML** -- WordprocessingML
* no prefix -- standard MIME types, such as those used for image formats like
  JPEG
