LMSGetValue and Activity Attempt Count in SL course

Hello,

While looking into the different calls and variables available for use to get information from the LMS into a course, I stumbled onto a variable called Activity Attempt Count. I wanted to try something out with it, but wasn't sure what it's syntax would be. On the SCORM.com site, it only lists the variable naming but not how it would look in code. Comparing it to other variables, I assume it would be something like activity_attempt_count, but wanted to check if anyone has any experience with this variable and how it would be used.

If it is a variable we can read from the LMS into a SL variable, we had some ideas on how we might use it but wanted to check how it's used and if its possible to use in SL. Thank you.
