I think this usage of "Type 1" uniqueness is the norm. However, rather than "one extra candidate", it's actually "one cell with one or more extra candidates."

Is there then any definition or use of terminology for Type 2, 3, etc. on any deadly pattern other than a unique rectangle?

Don't recall seeing any, but it seems such a natural extension, I wouldn't be surprised to learn of their existence, especially as to usage.

Keith,
I recall finding a Type 1 MUG some time ago but I do not have a reference to it.

You may be referring to this exchange last spring. The last post in that thread has some links related to this topic.
