This specification seeks to remedy that in the context of <a class="def" href="#glossary-user-agent">user agents</a> conforming to DOM Level 3 Events by providing discrete feature strings and clear guidelines for the circumstances under which a <a class="def" href="#glossary-user-agent">user agent</a> must or must not report in a positive manner when queried for support of the feature which that feature string represents.</p>
           <p>DOM Level 3 Events introduces compositional feature strings, which are base feature strings combined with extended feature strings, a new mechanism for testing support for each specific feature, rather than relying on modules-level feature strings.

         <p>This module defines the feature MutationEvents 3.0 and depends on the feature Events 3.0.</p>
         <p>The mutation and mutation name event modules are designed to allow notification of any changes to the structure of a document, including attribute, text, or name modifications. It may be noted that none of the event types associated with the modules are designated as cancelable. This stems from the fact that it is very difficult to make use of existing DOM interfaces which cause document modifications if any change to the document might or might not take place due to cancelation of the resulting event. Although this is still a desired capability, it was decided that it would be better left until the addition of transactions into the DOM.</p>

For example, if an element is created but not yet inserted into the document, then an existing element located in the document shall be moved from its current location to be a child of the new element, there must be one mutation event, for removing the existing element from its previous location, but no event must fire for insertion of the element into the new element, regardless of any assigned mutation event listeners.</p>
