Well, I'm not building a plugin - but rather a bash script, both to keep 
it simple, and to further my knowledge.

So,
My script is working insofar as I am getting a VRT that QGIS (v2.5.0 rev 
b43d131 and gdal/ogr 1.11.0) loads, _but it comes in with zero elements._
For guidance I am using http://www.gdal.org/drv_vrt.html

I have tried wrapping each SHP file in it's own <OGRVRTLayer 
name:shpname>, and below is the version having a global OGRVRTLayer name.

Can someone please give me some pointers as to what is incorrect or 
missing in my VRT file?
TIA,
