The xrootd protocol spec (v3.1.0) describes how kXR_mkdir and kXR_open operations both have an options field. In both cases, this field act as a bit mask for flags that affect the behaviour of the respective commands. According to the spec, both accept the value kXR_mkpath with similar semantics:
kXR_mkdir:
http://xrootd.org/doc/dev45/XRdv310.htm#_Toc464248821
kXR_open:
http://xrootd.org/doc/dev45/XRdv310.htm#_Toc464248823
This is wrong as the xrootd code uses bit-0 in kXR_mkdir options to indicate parent directory elements should be created, whereas kXR_open uses bit-8 for the same behaviour. Therefore, the flags cannot be described using the same constant (kXR_mkpath).
Further, these constants appear not to be defined anywhere in the spec. This makes the spec. incomplete.
