How do you state every wednesday in effectiveTime in CDA?

Hey Jens--maybe you've already gotten an answer for this in the past week, but I think the upshot is to use a PIVL_TS with @alignment="DW":

<effectiveTime xsi:type="PIVL_TS" alignment="DW">
    <phase>
        <!-- Apr 22 2020 was a Wednesday -->
        <low value="20200422" />
        <width value="1" unit="d" />
    </phase>
    <period value="1" unit="wk" />
</effectiveTime>

I'm not sure whether it's better to include the width or whether that would imply "all day every Wednesday" though.

When I asked the question I didn't realize that I was restricted to the use of IVL_TS (forgot to mention) at the time of posting

Since my use is in observation and not substanceAdministration, I can only use IVL_TS

Ah, gotcha. Yeah, I don't think there's any way to represent a periodic interval in an observation/effectiveTime.
