I All,

recently I have read SML specification and in particular sml reference mechanism in XML instance document. However I don't understand the reason of introducing a new mechanism instead of using xlink.

Are there some advantages in using sml:ref?
If yes...which ones?

That is to say...about this example:

<EnrolledCourse sml:ref="true">
    <sml:uri>     http://www.university.example.org/Universities/MIT/Courses.xml

Why not like that?

    <environment xmlns:xlink="http://www.w3.org/1999/xlink" 
        <course xlink:type="locator" xlink:label="course"
	    #xmlns(u=http://www.university.example.org/ns)		    xpointer(/u:Courses/u:Course[u:Name='PHY101'])"/>

Best regards..
