Where are the templates stored?
the documentation  does not answer my question. For example "#d-i
netcfg/dhcp_options select Configure network manually"...
How am I supposed to know there is another option would be "Do not
configure network at this time"? That's not in documentation, that's
only found on google which is difficult and I still do not find all
I am looking for the templates.  I'd like to have a list
- possible values.
Where can I find this? In which source package is it?

You've preseeded partman-basicfilesystems/no_swap the wrong way round
(although it might be hard to infer that from the template name alone).
The full template is as follows:
_Description: Do you want to return to the partitioning menu?
You have not selected any partitions for use as swap space. Enabling swap
space is recommended so that the system can make better use of the
available physical memory, and so that it behaves better when physical
memory is scarce. You may experience installation problems if you do not
have enough physical memory.
If you do not go back to the partitioning menu and assign a swap partition,
the installation will continue without swap space.
