Hello Johannes,
  
  I consider your first \XMLifequalelse command a bit strange. This  command is intented to be used if you want to convert the attribute  values into something else (e.g. "yes" into "packed").
  If you need the unmodified parameter value, simply use \XMLpar.
  So e.g.:
  
  \startitemize[ \XMLpar{list}{setup}{}, \XMLifequalelse{list}{packed}{yes}{packed}{unpacked} ]
  
  Of course "setup" should be a required attribute of <list> (in  your DTD), otherwise it would lead to something like  \startitemize[,packed] which obviously wouldn't work at all. 
  If it's not the case, I'd use \doifXMLparelse:
  
  \doifXMLparelse{list}{setup}{%
    \startitemize[ \XMLpar{list}{setup}{}, \XMLifequalelse{list}{packed}{yes}{packed}{unpacked} ]%
  }{%
    \startitemize[1, \XMLifequalelse{list}{packed}{yes}{packed}{unpacked} ]
  }

Subject: [NTG-context] ConTeXt, XML, multiple attributes evaluation

Hello again,

Another one:
I'm trying to expand 
>\defineXMLenvironment [list]%
> {%
>  \expanded{%
>   \startitemize%
>    [%
>     \XMLifequalelse{list}{packed}{yes}{packed}{unpacked}%
>    ]%
>  }%
> }%
> {\stopitemize}

which can deal with things like
><list packed="yes">
> <item>
> </item>
></list>

To something able to deal with multiple attributes (a "setup" statement for
now):
><list packed="yes" setup="n">
> <item>
> </item>
></list>

I have tryed multiple incarnations of
>\defineXMLenvironment [list]%
> {%
>  \expanded{%
>   \startitemize%
>    [%
>     \XMLifequalelse{list}{setup}{n}{n}{},%
>     \XMLifequalelse{list}{packed}{yes}{packed}{unpacked}%
>    ]%
>  }%
> }%
> {\stopitemize}

but this doesn't work ...

Can anybody give me any pointers here?

Thanks for time and help,

Joh
