[Qgis-developer] Vector equivalent of a VRT

No that's OK

You likely need to add the attribute  relativeToVRT="1" in <SrcDataSource> so 
that the paths are interpreated relatively to the VRT file.

i.e.

 <SrcDataSource  
relativeToVRT="1">2730/2730_RIVER_LINE_2006_06.shp</SrcDataSource>

You can check with "ogrinfo -al /path/to/your.vrt" to see if it works and if 
there are error messages.
