> This url is mostly not set, anyway not for each child module. To solve this
> issue I did the following in method *getDecorationModel* of
> *org.apache.maven.plugins.site.AbstractSiteRenderingMojo*:
> If the parent model descriptor exists, the current and the parent model will
> be assembled by using following url parameters:
> If parent's url is null but child's not child's url will be used for parent.
> If both urls are null the "url" "./" will be used for current and parent.
> See appended patch.
