How many security levels can I add to one Issue Security Scheme?

[Jeremy Price]

I just want to know how many levels I can apply to an individual issue security scheme. I was able to get to 10 and didn't want to keep creating levels, as there maybe no limit to them.

I was unable to find any documentation on this. Seeing if any of you all might have maybe15 or 20 levels on a security scheme or if you know the exact answer.
