Wrong display of "Kontext" in viewer for years and issues of newspaper

[stweil]

The official DFG Viewer shows correct metadata: https://dfg-viewer.de/show?tx_dlf%5Bid%5D=https%3A%2F%2Fdigital.ladenburg.world%2Fdata%2FNeckar-Bergstrass-Post%2Fmets_1925.xml

Titel
    Neckar-Bergstraß-Post
Kontext
    Neckar-Bergstraß-Post
Erscheinungsort
    Ladenburg

A test installation with TYPO3 11 and the official master branches shows wrong metadata for "Kontext": http://localhost/viewer?tx_dlf%5Bid%5D=https%3A%2F%2Fdigital.ladenburg.world%2Fdata%2FNeckar-Bergstrass-Post%2Fmets_1925.xml

Titel
    Neckar-Bergstraß-Post
Kontext
    Neckar-Bergstraß-Post >
Erscheinungsort
    Ladenburg

Note the additional ">". The HTML code shows a wrong encoding (missing ";"):

<dt>Kontext</dt><dd>
        Ladenburger Wochenblatt &gt</dd>

The wrong "Kontext" is not only shown in the calendar view for a single year, but also in the viewer for a single newspaper issue.

I noticed the wrong encoding &gt instead of > while I validated the HTML code with the W3C validator.

Unrelated question: I wanted to test SRU, added a <dv:sru> entry to my METS files, but don't see any effect in the DFG Viewer (neither at dfg-viewer.de nor in a local test installation). How can I get a search field? Is there a working example somewhere?

Another display error is shown in the viewer for the whole newspaper ("Gesamtausgabe", anchor METS file): http://localhost/viewer?tx_dlf[id]=https%3A%2F%2Fdigital.ladenburg.de%2Fdata%2FNeckar-Bergstrass-Post%2Fmets.xml

Titel
    Neckar-Bergstraß-Post

    01.11.1919 - 31.05.1941,
Erscheinungsort
    Ladenburg
Erscheinungsjahr
    1919-11-01

Note the comma behind "31.05.1941". Here is the HTML code:

 <dt>Erscheinungsverlauf</dt>
 <dd>01.11.1919 - 31.05.1941</dd>,

I found the solution in the source code of slub_digitalcollections, not in the documentation (METS-Anwendungsprofil_2.3.1.pdf, SRU-ALTO-Anwendungsprofil_1.0.pdf). The SRU entry is expected below <mets:digiprovMD>:

  <amdSec ID="amd_01">
    <digiprovMD ID="digiprov_01">
      <mdWrap MDTYPE="OTHER" OTHERMDTYPE="DVLINKS">
        <xmlData>
          <dv:links>
            <dv:sru>http://HOST/PATH</dv:sru>
          </dv:links>
        </xmlData>
      </mdWrap>
    </digiprovMD>

@sebastian-meyer, is this a documentation issue, or did I look at the wrong place?
