What is the purpose to set Term ID/Caption ID to zero in custom solution or menu XML file of Exact Synergy Enterprise?
===

We have a requirement to make our business component multi-language. 

Documentation suggests us to use `termid`/`captionid` for translations. However we find `termid`/`captionid` set to `zero` in many places of SDK and framework itself.

What is the purpose to a `termid`/`captionid` to `zero`?
