[NTG-context] \defineseperatedlist and working with variables and merging fields

Attached a tex file and the generated PDF. The first table is what I am trying to do. The second table is an example about what I would like to accomplish. I have two problems. Because there will be a lot of tables I like to use a variable, so that changes can be done in one place. That is why I would like to use: \getvariable{desc}{fieldHeading} on the third line of the table. But then I get one column instead of five. (The third is what I get, the fourth what I would like to get.) In the first and last two rows I would like to have the field take the complete row. Just like the example in the table under it where I use Is this possible? -- Cecil Westerhof
