 Yes, the preferred style.

***
 This is not merely tolerated, but perfectly in order. 
 It is a matter of style.
* * *

>  x Foo (ICBN preferred alternative)

***
 No, this is disallowed by the ICBN (Art. H.1). This is 
 something that is only to be used when out of reach of 
 a computer, as in when using a typewriter.

***
 Again, disallowed by the ICBN.

>  xFoo (again, probably tolerated, but not sure...)

***
 Again, disallowed by the ICBN. 
* * *

***
In that case it is a good idea to keep in mind that this extra
DwC field for hybrid indicator would be needed at each of the
three levels.
