"tagType" and "typeId" are not in Tag Properties Documentation

I was writing a script to find out if a list of tags are UDT instances and what type of UDT.
I’ve noticed that the tag properties documentation (Tag Properties - Ignition User Manual 8.1 - Ignition Documentation) doesn’t mention the tagType or typeId properties, which are valid.

By the way, this link points to version 8.0. I think you should aim for 8.1:
