Templates as Extensions in Calc

I noted in the document CG4004 - Using Styles and Templates in Calc there
is a discussion about installing Templates using the Extension Manager. So
far I have not had any success in finding any Templates packaged in this
manner. Am I just looking in the wrong places, or are most Templates really
just offered as *.ots files to manually install?

Thanks,

I have never packaged or used templates packages as an extension. If you want to test one, however, take a look at this:
