... but first make sure that the tools you wish to process the resulting 
GML with are actually capable of handling that amount of data ;-)

Depending on what kind of data is required, one could also create a 
PostGIS database (using Osmosis or osm2pgsql), and then make GML from 
that using ogr2ogr.

I think that osm2pgsql will process the full planet in a few hours if 
you have 16 GB of RAM, or within about a day in "slim" mode if you have 

But I warmly recommend getting a country extract first before embarking 
on conversion jobs that might well take a week to complete, and then 
finding out that one wanted something slightly different ;-)
