*Title: Modifications needed to fix bug #8553: wrong object embedding by "eznode"
 if you have more locations.

*Documentation:

The next table shows which templates are used to render XML tag, depending on
tag's name and used protocol (eznode or ezobject).

These templates reside in templates/content/datatype/view/ezxmltags directory.

  +------------------+------------------------+------------------------+
  | Tags \ protocols | ezobject               | eznode                 |
  +------------------+------------------------+------------------------+
  | <embed>          | embed.tpl              | embed_node.tpl         |
  | <embed-inline>   | embed-inline.tpl       | embed-inline_node.tpl  |
  +------------------+------------------------+------------------------+

embed.tpl uses 'content_view_gui' template operator to display an object while
embed_node.tpl uses 'node_view_gui' operator. So different templates are
used to render an object (templates/content/view/... and templates/node/view/...)
dependning on eznode or ezobject protocol is choosen.
