What you're asking for there is the value of a "description" property of
whatever $xy points to.
If $xy was a DateTime then you can do this:
PS > $xy.Year
2006
But in your case $xy is a string ("orange"), and System.String doesn't
have a property called Description.
I guess get-variable is the only way to get to this "metadata" attached
to a variable in PS.
