acro calling an unknown kernel message

[FrankMittelbach]

In the code you find

    group         .code:n     =
      \str_case:nnTF {#1}
        { {true} {} {false} {} }
        { \use:c {bool_set_#1:N} \l__acro_cite_group_bool }
        { \msg_error:nnn {kernel} {boolean-values-only} {group} } ,

Trouble with this is

• the documentation indicates that cite/group defaults to cite/group=true which is not the case (and in my opinion a pity, i.e., it should be supported)
• but worse: if you try cite/group without a value you get this error message:

  
  LaTeX3 Error: Unknown message 'boolean-values-only' for module 
  'kernel'.

For immediate help type H . ...

not nice :-)
