A couple of points to help head off the next questions at the pass: 

1) You should have $id == the domain id (returned from xi_create), e.g 
   id=`xi_create $size $name`

2) At the end you need to start the domain, e.g. 
   xi_start $id

xi_phys_grant (like most of the internal tools) isn't really designed 
with user friendliness in mind; if at all possible you should try to 
use xenctl, e.g. 

xenctl physical grant -phda3 -w -n$id 

will grant read-write access to the partition /dev/hda3 to the domain
that's just been created. This doesn't go near the xml stuff which 
you had some unspecified problem with. 

If you really want to us xi_phys_grant directly the  typing just 
xi_phys_grant should get you the error message: 

Usage: xi_physdev_grant_new <r/rw> <domain> <device> <start sector> <n_sectors> 
<partition>

The first two are fairly obvious; the <device> is the linux device
number in question (e.g. for partition /dev/hda3 this would be 0x0800) 
the start_sector is the first sector that partition (see /proc/partitions) 
and n_sectors the number of them (ditto). Finally partition is the
partition number (e.g. in the case of /dev/hda3 it would be 3). 

HTH.
