This service provides access to the Macros and Macro containers via the
XBrowseNode interface. XInvocation is an optional interface that is used
to execute macros, or to create/delete/rename macros or macro containers.
This interface represents a node in the hierarchy used to browse
available scripts.
Objects implementing this interface are expected to also implement
com.sun.star.beans.XPropertySet and, optionally,
com.sun.star.script.XInvocation (see the Developers' Guide for
more details).
