Modelsim covergroups with PSL

I am wondering if it is possible to create Modelsim (DE 10.0a) covergroups with PSL(VHDL).

I couldn't find any documentation, and I'm starting to have doubts about its feasibility.

I know how to create cover points, but is there a keyword that I missed or a kind of structure type that would do the job?

Or is SystemVerilog (and Questasim) mandatory for that?

Thank you.
