I was looking at a package I made, a completely empty one, includes this
XML in the package JAR

<package-folder id="9" name="Global Configurations">
<description></description>
<children/>
</package-folder>
<package-folder id="2" name="Resources">
<description></description>
<children/>
</package-folder>
<package-folder id="5" name="Provisioning">
<description></description>
<children/>
</package-folder>
<package-folder id="1" name="Policies">
<description></description>
<children/>
</package-folder>
<package-folder id="3" name="Jobs">
<description></description>
<children/>
</package-folder>
<package-folder id="4" name="Entitlements">
<description></description>
<children/>
</package-folder>
<package-folder id="7" name="Notification Templates">
<description></description>
<children/>
</package-folder>
<package-folder id="8" name="ID Policies">
<description></description>
<children/>
</package-folder>
<package-folder id="6" name="Files">
<description></description>
<children/>
</package-folder>

What do you think the last one, id=7 and name=files might reference?

Resources is covered. Package Prompts, are they DirXML-Resource files?
Yep, just checked, content type is pkg-prompt+xml.

DS-Object is also a Resource, application/vnd.novell.dirxml.ds-object+xml

I wonder.

Did not know you could include ID Policies either. I am not sure how to
even make one of those... Now I kind of want to find an example package
that has a Files or ID Policies defined.

Anyone know how to grep within ZIP files?
