[Gdal-dev] DEM 'no_data' specification

Does GDAL allow user specification of a 'no_data' value for DEM? If
not, would it be practical/possible to add this?
My idea is this:
Images are a perfect media for porting information to mainstream,
non-GIS applications, e.g. Matlab, image analyzers, etc. Since 'no_data'
specifications are merely position holders in the file, allowing the user
to specify their own value would resolve some data scaling problems
in other applications, as well as allowing construction of visually accurate
data images .
