These will appear on the attorney's Bio page.
They are also used to populate the Attorneys on the Practice pages

These are used for the Attorney search page.
Per attorney, for every tag there should be a practice-value.

If they are simply different spellings of the Practice, they should be tagged with the Practice with the usual spelling, and have the practice-value added, and then also write in the unique spelling of it.
But if it's a practice that is not in the Practice collection list, then all you need todo is write it in.
