The following code fails with the current standalone
(ConTeXt  ver: 2014.01.14 22:36 MKIV beta  fmt: 2014.1.14  int: 
english/english), but works with TL2013:

        \setuppapersize[A8][A8]
        \definelabel   [Qb]
                        [
                          text=,
                          alternative=inright,
                          way=bytext,
                          headstyle=\ssxx,
                          headcolor=darkgray,
                        ]
        \starttext
        \Qb[labelname]This is some text.

        As in \in[labelname].
        \stoptext

The problem appears to be with the alternative= key, which I do not see 
in the wiki for \definelabel but take to be the MKIV equivalent of the 
location= key (as described on the wiki for \setupdescriptions and 
presented in numerous examples on the mailing list). The location= key 
appears to be ignored, although it does not otherwise fail, when used in 
this snippet.

The example produces:

The same code in TL2013 produces:


Any clues about how to fix this will be greatefully accepted.
