Basic policy question

I have another question: when you are performing policy to claim mapping, can you use regular expressions to evaluate the claim?

and what happens if for example “mycustomscopeclaim” contains this:

mycustomscopeclaim: abc123 def567 xyz999

will Tyk correctly find def567 if it is listed under “Scope to policy mapping” ? Can I use regular expressions or wildcards to define the claim? For example “def*” will match def567?
