JT pointed out that the redirect links are not working in the current MoEML, and on investigation it appears that we never implemented them at all. I did so, hastily:
- Each redirect (from redirects.xml) generates a special page with a meta refresh tag that points to the new URL; that will work on static versions of the site.
- An XQuery intervention in doc.xql in eXist notices such HTML content and intercepts it, sending a 301 instead; that will help with search engine index updating.
Took a while to figure out how to get the first part to be valid; it turns out that the single quotes that used to be normal around the URL are now invalid, and you need to provide this formulation:
<meta http-equiv="refresh" content="0; URL={$targId}.htm" />
