Some other articles:

Donald Bamber; Jan P. H. van Santen. How many parameters can a model
have and still be testable? Journal of Mathematical Psychology
Donald Bamber; Jan P. H. Van Santen. How to assess a model's
testability and identifiability. Journal of Mathematical Psychology
Schmittmann, V. D., Dolan, C. V., Raijmakers, M. E., & Batchelder, W.
H. (2010). Parameter Identification in Multinomial Processing Tree
Models. Behavior Research Methods , 42, 836-846.

The Schmittmann et al., article has a lot of useful citations and two
worked examples, contrasting global vs. local identification.
