OpenSearch description

[Zash]

Having an OpenSearch description document allows some software (e.g. Firefox) to automatically pick up on search features on a page.

Specification appears to be this:
https://github.com/dewitt/opensearch/blob/master/opensearch-1-1-draft-6.md

Example minimal description document:

<?xml version="1.0" encoding="UTF-8"?>
<OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/">
  <ShortName>search.jabber.network</ShortName>
  <Url type="text/html" template="https://search.jabber.network/search?q={searchTerms}"/>
</OpenSearchDescription>

And this snippet in the HTML to reference it:

<link rel="search" type="application/opensearchdescription+xml"
 href="/opensearchdescription" title="search.jabber.network">
