Is it possible to make a jsdoc like the following?

/**
 * Does something with an alphanumeric string
 * @param {string/^[a-z0-9]+$/i} the string that must be alphanumeric
 * /

I can't see anything on the types page for JSDoc, but I've found that site difficult to navigate before and I couldn't find a third party library, making me think JSDoc come with this?

Is this possible without pulling in external libraries?
