 JSON-LD allows <tref>context</tref> to be applied to JSON data. Applying
 <tref>context</tref> to JSON data allows it to be expressed in a way that
-is specifically tailored to a particular person or application. If an
-application or person wants to use data that was created using a different
-<tref>context</tref> than they are programmed against or used to, it
-would be very convenient if it were possible to transform the data to
-their own <tref>context</tref>. Instead of requiring JSON-LD
-processors to write specific code for every imaginable <tref>context</tref>
-switching scenario, it is much easier to write a single
-algorithm that can remove any <tref>context</tref> (and another that
-can subsequently apply any <tref>context</tref>). The algorithm that
-removes <tref>context</tref> is called <tdef>expansion</tref>.
