Faced with an unquoted string as an attribute argument referring to another note, if the string starts with a forward slash Tinderbox will assume the string is a Tinderbox paths.
Unquoted strings as arguments:
$MyString(Some note)

In contrast, a quoted string argument will be assumed to be a $Name value.
$MyString("Some note")
