OAC embedded `<dao>` content: convert to "Online items" links (in lieu of embedding the content)?

[aturner]

ArcLight evidently has a configuration to display and embed content referenced from a <dao> HREF. The source HTML doesn't include any provisions for alt-text, and may hence not be accessible:

https://oac.cdlib.org/findaid/ark:/13030/c8668mv4_aspace_8b5b5819fe1e952ae4262a83637d922f
https://oac.cdlib.org/findaid/ark:/13030/kt0z09r4w0_aspace_7bff1ff4f4a16542be1dae4a9a6a06e7
https://oac.cdlib.org/findaid/ark:/13030/kt5k4036nc_aspace_ref147_tt7

Here's the EAD source encoding:

<dao actuate="onrequest" href="https://purl.stanford.edu/bn731cs7403" show="new" title="Bay Area Radio Drama digital files folder listing&#10;" linktype="simple">

<dao actuate="onrequest" audience="external" href="https://purl.stanford.edu/zv081yq3521" show="new" title="ars0065 Digitized Sound Recordings on Hard Drive" linktype="simple">

<dao xlink:actuate="none" xlink:href="https://purl.stanford.edu/kw973pp2772" xlink:role="audio-master" xlink:show="new" xlink:title="Reel 94" xlink:type="simple">

In testing out <dao> encoding permutations on OAC -stg, it looks like the content will be embedded if the tag has all 3 of these attributes: ACTUATE, SHOW, LINKTYPE:

1. EAD: https://cinco-stage.s3.amazonaws.com/media/ead/ms008-amy-test_XoWnVHq.xml
2. Display: https://oac-stg.cdlib.org/findaid/ark:/13030/c8pr84bg_aspace_ref306_39x

Proposed solution, until we can further assess the accessibility: convert the display to "Online item" links, as with any other <dao> HREF element?
