noviski:thanks for the tip. At the moment, those animations don't want to load. [Got a "Cannot display this page" message]. I'll try again later. What I did do, was to follow the link on the table of joint rotation limits, that you posted. This table is from "Digital Character Animation", which I bought...which is a great book! A $55.00US book, but used copies available from amazon.com for $18.00. A lot of very good information.
