Question about doctype

The specification document lacks a simple example of how an OASIS file
matching the specification would look like.

For instance, what should the DOCTYPE tag look like (assuming there should be one)?
In OO it was like
<!DOCTYPE office:document-content PUBLIC "-//OpenOffice.org//DTD OfficeDocument 1.0//EN" "office.dtd">
<office:document-content ...>

Should OASIS documents have a DOCTYPE tag? If yes, what should the public ID
and the system ID for it, to somehow refer to the OASIS open office specification?
