According to SHP specification, Mmin and Mmax is equal to 0.0, if not
Measured type. If the shapefile is empty (that is, has no records), the
values for Xmin, Ymin, Xmax, and Ymax are unspecified. Mmin and Mmax can
contain "no data" values for shapefiles of measured shape types that
contain no measures.
However, SHP provider always uses "no data" no matter shp file contrains
measured shape types.
