[basex-talk] csv:doc - interpretation of option values

Dear BaseX people, a small observation, which might be regarded as a bug (perhaps not). It is about the interpretation of options passed to function csv:doc. I set the 'header' option like this: let $options := map{'header': //header/data()} with the confusing result that the option is ignored, although the comparison     $options?header eq 'yes'  yields true. If I replace data() with string(),  let $options := map{'header': //header/string()}

the option works as expected. Kind regards,Hans-Jürgen
