Both of the above URLs are identical.  I think you meant:

URL1 -
http://xapi.openstreetmap.org/api/0.6/node[memorial:type=stolperstein][bbox=5.5,47.4,15.0,55.3]<http://xapi.openstreetmap.org/api/0.6/node%5Bmemorial:type=stolperstein%5D%5Bbbox=5.5,47.4,15.0,55.3%5D>

and

URL2 -
http://xapi.openstreetmap.org/api/0.6/relation[name=Stolpersteine][bbox=5.5,47.4,15.0,55.3]<http://xapi.openstreetmap.org/api/0.6/relation%5Bname=Stolpersteine%5D%5Bbbox=5.5,47.4,15.0,55.3%5D>

Unless I'm mistaken, URL1 returns a file containing the following entry:
<relation id='407359' user='Netzwolf' uid='32786'
timestamp='2010-03-05T21:26:43Z' version='75' changeset='4044847'>
  </relation>

Can you please open your two OSM files and check them before you add more
!!!!!!'s to your emails ;-)

Cheers,
