Entity files' references in mathml3 dtd

In the mathml3.dtd file I see that the entity files are referenced like this (for instance):

<!ENTITY % isobox PUBLIC "-//W3C//ENTITIES Box and Line Drawing//EN" "entities/isobox.ent">

but the entity files themselves have comments saying their public identifiers should end with //XML:

<!-- 

       Public identifier: -//W3C//ENTITIES Box and Line Drawing//EN//XML
       System identifier: http://www.w3.org/2003/entities/2007/isobox.ent

     The public identifier should always be used verbatim.
     The system identifier may be changed to suit local requirements.

     Typical invocation:

       <!ENTITY % isobox PUBLIC
         "-//W3C//ENTITIES Box and Line Drawing//EN//XML"
         "http://www.w3.org/2003/entities/2007/isobox.ent"
       >
       %isobox;

-->

The mathml3.dtd seems to be wrong here (I think the identifiers used to be without //XML before)...  right?
