Introduction to XML For Web Developers
General Entities  

General entities look something like:

    <!ENTITY NAME "text that you want to be represented by the entity">

which might look like the following in the real world:

    <!ENTITY full_name "Diego Ramirez Valenzuela Martinez Perez the 5th">

NOTE: You can specify an entity that has text defined external to the document by using the SYSTEM keyword such as:

    <!ENTITY license_agreement
       SYSTEM "http://www.mydomain.com/license.xml">

In this case, the XML processor will replace the entity reference with the contents of the document specified.
