If the option 'Enable archives' is selected for a product attribute, then the layered nav widget can also be used to filter that archive.
However the widget then doesn't work correctly in 'List' and 'OR' mode for that archive (although it works fine on the main shop page).
Example:
The attribute "product-type" is created and archives are enabled. It has values like "Courses", "One-to-one-tuition", "Equipment rental" and so on. Another product attribute "teaching-level" is created which uses values of "Beginner", "Intermediate" and "Advanced".
When the archive http://www.domain.com/pa_product-type/courses/ is visited the correct products are displayed. A layered nav widget is added in 'List' and 'OR' mode for the attribute 'teaching-level'. Clicking on any of "Beginner", "Intermediate" and "Advanced" will work fine the first time as the links are correctly generated in the form http://www.domain.com/pa_product-type/courses/?filter_teaching-level=advanced&query_type_teaching-level=or. (Advanced used for the example). However once one has been clicked, the links generated are now incorrect - they are in the form http://www.domain.com/?taxonomy=pa_teaching-level&term=advanced&filter_teaching-level=advanced%2Cbeginner&query_type_teaching-level=or.
Using get_queried_object instead of get_query_var fixes the problem.
Updates to layered nav to considerably improve speed on sites with large product databases (10k+). This method has seen speed improvements as notable as taking a 30 second plus load time of a /shop page with layered nav, down to 4 seconds.
