prop=imageinfo: give empty tag for files without metadata
Open, LowestPublic

Description

For files without metadata the api shows:

<imageinfo>
  <ii metadata="" />
</imageinfo>

It is possible to change this to

<imageinfo>
  <ii>
    <metadata />
  </ii>
</imageinfo>

Or an other style? The current is wrong and bad to detect.

Thanks.

Seems to be unfixable without versioned api (see blocking bug 38891), setting Importance to Lowest to avoid a WONTFIX.
