Ah! I didn't realise such a format was among the actually used ones.
Shouldn't the EPSG database list this format in the section 
Or is it a proprietary format, only used by Trimble?
Anyhow, wouldn't it be more productive if the PROJ command line had a flag, 
denoting the format of the DMS input and output?
