When writing your own templates, you can parse one of these two includes in order to get references to the most commonly used pieces of information:

schema.include.vm when writing a perschema template
table.include.vm when writing a pertable template

Just take a look at the existing templates to get an idea of what is made available to you.

Of course, we would greatly appreciate your new templates.  If you think they may be of common interest, just post them as a Feature Request and we will include them in the next release.
