+/** specifies actions which can be transported with content events.
+
+ <p>
+ The situations under which contents will send ContentEvents of the various
+ action types are described below. The description is broken into a list of
+ useful definitions, a list of events that happen to contents, and a list of
+ reactions taken by contents in response to those events.
+ </p>
+
+ <p>
+ The definitions are as follows:
+ </p>
+
+ <table border =1>
+ <tr><td>D1</td><td>A content C has an identifier id(C).</td></tr>
+ <tr><td>D2</td><td>A content C is in one of two states, Alive or Deleted.
+ </td></tr>
+ <tr><td>D3</td><td>A folder content F has a set of children H(F) that is a
+ set of content identifiers. For example, an "open"
+ command will usually return a subset of the contents
+ denoted by H(F).</td></tr>
+ </table>
+
+ <p>
+ The events that can happen to contents (and that are of interest in this
+ context) are listed next. Note that "event" here does not mean an
+ ContentEvent, but rather some event that occurs either because some content
+ processes a command, or because a content gets informed about a relevant
+ change in the underlying system it represents.
+ </p>
+
+ <table border =1>
+ <tr><td>E1</td><td>The identifier of a content C changes from id1(C) == A
+ to id2(C) == B, denoted as E1(C: A->B). For example,
+ this event may occur when content C processes a
+ "setPropertyValues" command changing its "Title" property,
+ or when a folder that hierarchically contains C changes
+ its identity.</td></tr>
+ <tr><td>E2</td><td>The state of a content C changes from Alive to Deleted,
+ denoted as E2(C). For example, this event may occur when
+ content C processes a "delete" command, or when a content
+ representing an IMAP message gets informed by the IMAP
+ server that the message has been deleted.</td></tr>
+ <tr><td>E3</td><td>The set of children of a folder content F is enlarged by
+ some identifier A (that was not previously in that set,
+ i.e., !(A in H1(F)) && (A in H2(F))), denoted as E3(F, A).
+ For example, this event may occur when a new content
+ created at folder F processes its "insert" command, or
+ when a folder representing an IMAP mailbox gets informed
+ by the IMAP server that a new message has arrived at that
+ mailbox.</td></tr>
+ </table>
+
+ <p>
+ Finally, the list of reactions taken by contents in response to the above
+ events gives a description of what kinds of ContentEvents are sent in which
+ situations:
+ </p>
+
+ <table border =1>
+ <tr><td>R1</td><td>E1(C: A->B) results in C sending an EXCHANGED
+ ContentEvent, which then results in the following: All
+ folders F that used to have A as a child, but will not
+ have B as a child, i.e., (A in H1(F)) && !(B in H2(F)),
+ send a REMOVED ContentEvent.</td></tr>
+ <tr><td>R2</td><td>E2(C) results in C sending a DELETED ContentEvent,
+ which then results in the following: All folders F that
+ used to have A as a child, but will not continue to have
+ A as a child, i.e., (A in H1(F)) && !(A in H2(F)), send
+ a REMOVED event.</td></tr>
+ <tr><td>R3</td><td>E3(F, A) results in F sending an INSERTED event.</td></tr>
+ </table>
