7.8.1 : hst:content node of type facetselect below site nodes can better be replace with property on hst:site node
The 7.8.1 by default does not have a hst:content node below the
hst:site node any more. Instead, there is a property 'hst:content' on
the hst:site node that is either the uuid of the real content node
*or* the absolute jcr path to the content node. The absolute path is
preferable as this is also how the channel manager creates new
channels with the 7.8.1, however, up to the developer.
Thus, instead of have the facetselect (filtered mirror) as content entry point
