Please note that version 7 is very old. If you are working with DITA and you can upgrade I would suggest doing so as the DITA authoring solution has been improved a lot since version 7. It also has improved support for these specific DITA features. The current release is 10.
If you are interested in XML entities or XInclude then there is less reason to upgrade as these standards have not changed for many years so the features that support them in XMetaL Author have not needed to be updated. I would still upgrade anyway however as there have been many hundreds of other improvements in the software since version 7.
