Hello!

A Markdown document resembles the following:

::: {.concurrent title="Berth 5" location="San Diego"}

Text Goes Here

:::

::: {.concurrent title="Road" location="Beale AFB"}

Different Text Goes Here

:::

The XHTML generated from that document resembles:

Text Goes Here

</div>

Different Text Goes Here

</div>

Environments for the DIV element gets translated using:

\startxmlsetups xml:div
\start[\xmlatt{#1}{class}]\xmlflush{#1}\stop
\stopxmlsetups

This creates "\startconcurrent" and "\stopconcurrent", which are later defined using "\definestartstop[concurrent]".

I'd like to dynamically define all the data- attributes to make key/value pairs accessible from the document. For example, I have this:

\definestartstop[concurrent][
before={%
\blank[big]%
\setMPtext{1}{Berth 5}%
\startTextConcurrentFrame},
after={\stopTextConcurrentFrame\blank[big]},
]

I'd like to replace \setMPText calls with a reference to a dynamically created variable reference. For example:

\setMPtext{1}{\usermap[concurrent.title]}

\setMPtext{2}{\usermap[concurrent.location]}

I can verify the attribute values exist by exporting them to the document:

\startxmlsetups xml:div
title:\xmlatt{#1}{data-title} location:\xmlatt{#1}{data-location}
\start[\xmlatt{#1}{class}]\xmlflush{#1}\stop
\stopxmlsetups

How would you change the xml:div setup to create a map of its attributes as key/value pairs?

Thank you!
