Moreover:

The XPath expression "'$args'" evaluates to a string, "$args".

The XPath expression "$args" would evaluate to a reference to the variable (or parameter) $args.

In the example above, the template assigns a default value, the string "$args", to the $args parameter. This is not wrong, but it might be a bit confusing.
