<para>The function modifies the XML document of the given <parameter>source</parameter> XML tree entity by adding new siblings to
the node specified by the entity. Siblings will be added right after the node.
The <parameter>source</parameter> entity should be XML tree entity, not "persistent XML" entity.

<parameter>source</parameter> can not be an attribute entity or a root entity.
