Hello All,

I'm trying to render a table stored in XML JATS format (https://jats.nlm.nih.gov/archiving/) and eventually want to use the <colgroup> tag to setup column aligning from the @align attribute, e.g.,

    \setupTABLE [column] [\xmlpos{#1}] [align=\xmlatt{#1}{align}]

Including \xmlpos{#1} I get double the value returned, i.e.: the first element in colgroup returns 2, the second returns 4 etc.

Below is a MWE to show my issue. I show \xmlpos for each <col> tag in <colgroup>  above the table, which returns 2, 4, 6, 8 but I expected 1, 2, 3, 4. Am I missing something or is there another way I could do this?
