I'd like to know too, I thought what Guido described was correct. :)

'obtain' in English can be used in the sense of 'to be applicable' or
'to hold true'.

   3: be valid, applicable, or true; "This theory still holds".

'obtain' can be used intransitively since at least 1913:

>From Webster's Revised Unabridged Dictionary (1913) [web1913]:

  Obtain \Ob*tain"\, v. i.
     1. To become held; to gain or have a firm footing; to be
        recognized or established; to subsist; to become prevalent
        or general; to prevail; as, the custom obtains of going to
        the seashore in summer.
