'%"$%$! I mistyped the results. The actual results are:

(a) Microsoft IIS 5.0: (a1) no lock token: 400, (a2) bad lock token: 412.

(b) Apache/Moddav 2.0.49: (b1) no lock token: 400, (b2): bad lock token: 

(c) SAP Enterprise Portal 5SP6: (c1) no lock token: 412, (c2): bad lock 
token: 412.

(d) Xythos (Sharemation): see (c). (I also note that Xythos is returning 
invalid lock tokens)

RFC2616 treats exactly all "If-*" headers as defining preconditions. 
RFC2518 adds "If" (which is obvious) and also explicitly "Overwrite" 
(but at least it's clear about it). As RFC2518 nowhere states that the 
"Lock-Token" header expresses a "precondition", I'm leaning to 
favorizing Apache's behaviour (which is *not* what IIS does...).
