    <tp:docstring xmlns="http://www.w3.org/1999/xhtml">
      <p>The account manager is a central service used to store account
        details.</p>

      <p>The current account manager is defined to be the process that owns
        the well-known bus name org.freedesktop.Telepathy.AccountManager on
        the session bus. This process must export an
        /org/freedesktop/Telepathy/AccountManager object with the
        AccountManager interface.</p>

      <p>Until a mechanism exists for making a reasonable automatic choice
        of AccountManager implementation, implementations SHOULD NOT
        register as an activatable service for the AccountManager's
        well-known bus name. Instead, it is RECOMMENDED that some component
        of the user's session will select and activate a particular
        implementation, and that other Telepathy-enabled programs can
        detect whether Telepathy is in use by checking whether the
        AccountManager's well-known name is in use at runtime.</p>

    <!-- Missing functionality compared with NMC 4.x:
    * look up accounts by conditions (can be done client-side, less
      efficiently, so not a blocker)
    * global presence/... changes (can be done client-side, less efficiently -
      we should add this)
    * count used channels (what's this for?)
    * get "average" status (not well-defined, UIs can do this)
    * request channels (out of scope: Channel Dispatcher will do this)
    * register filters (completely out of scope: Channel Dispatcher again)

          This split between valid and invalid accounts makes it easy to
          ignore the invalid ones. The only things that should be manipulating
          invalid accounts are account-editing UIs, which might be able to
          rescue them.

          an Account already exists with the same display name, for instance by
          appending a number or the 'account' parameter. Account manager
          implementations SHOULD accept an empty string, but account editing
