I've added a sample skeletal  template for a Software Architecture Document  on the SAF page.

Few notes on the template:

• It is based on formality level required for large safety critical projects - most projects do not need this level of formality and can (and should) do with fewer views
• When there isn't a specific requirement by the customer to create an "official" architecture document - you probably want to have it just barely good enough
• The view list in this template is not an exhaustive list - these just the views I've used most often. (more on views on the next post :) )

Any feedback (either as a comment or to my email) is more than welcome
