I've done a little digging. The "const" keyword in the example
appears to indeed be a part of SystemVerilog and is similar to
the localparam in behavior. (Except it can be used in a few more
places.)

My SystemVerilog draft is too old to show this, but I think the
attribute assignment may include a type declaration along with the
assignment. That would mean that in principle the existing attribute
code can be extended in a SV-ish way to make the given code work.
I think *this* is what we want to do.
