 An even better alternative would be an alternate OS interface that would allow the user to select an area of the UK (draw a polygon as for PSMA), select the layers wanted, agree the licence, then transfer (FTP) to local machine. The next stage would be to unpack the used files into a standard directory structure, ready for subsequent use.

		+	The following are changes to the GML/GZ data such as used for MasterMap. With these changes, QGIS can style text in the "standard" OS manner.
		+
		+	*Translate OS "orientation" field (integer angle in 1/10 degrees) to "angle" as a float. [''angle = orientation / 10'']
		+	*Translate OS "font" field (integer in the range 0 to 3) to "qfont" as a string. [''The string value is the name of the font on the local PC'']
		+	*Translate OS "anchorPosition" (integer in the range 0 to 8) to "qPosition" as a string. [''The string value is the QGIS position string, e.g. Above Left'']
		+
		+
		+	For OpenData, the VectorData District technical specification says that the data is in GML 3.1.1, but it is actually delivered as shapefiles. VectorData Local is however supplied as GML (GZ), but specified as 2.1.2.
		+
		+	*"ORIENTATIO" always seems to be zero - should we just remove the attribute? It is also described in the VectorData District technical specification as being 0-359, so is different from the
		+	*"FONTHEIGHT" is described as points rather than map units for MasterMap. Simply using these values as map units results in too small text - possibly scale them?
		+	*"FONTCOLOUR" is a numeric field. The technical guide specifies standard colours, so these could sensibly be translated to standard QGIS colour strings. [''1 = Black, 2 = Blue, 3 = Green, 4 = Dark Blue'']
		+	*"FONTTYPE" is a numeric field giving an indication of possible font style. This could also be translated to a string specifying a local font. [''OS suggestions: 1 = Corbel, 2 = Corbel bold, 3 = Arial'']
