Core Expression that checks whether selection is zero-length string? [message #1718307]

I have the use case that I want to show a menu item only when the active "selection" is not just the curser, i.e., when it encompasses one or more characters. Is this possible out of the box, i.e., without writing my own IPropertyTester (which I would rather avoid, so not to incur unnecessary overhead for loading my plugin even if it is not needed)?

Unfortunately even a zero-length ITextSelection has a <count> of 1. And I cannot figure out how to make use of <equals>, to test for the empty string.

Any hints are greatly appreciated.
