<!-- Normalize the captured values before they go into attributes.
The capture blocks above are multi-line, so they arrive padded with
newlines/indentation, and some of them wrap their text in literal double
quotes to compensate for the content= attributes having been unquoted.
Strip both, then quote the attributes properly below: an unquoted
content= truncates the value at its first space, which is why every
langindex description used to render as a single word. -->
