Icon as link within property declaration
From semantic-mediawiki.org
Fragment of a discussion from Help talk:Properties and types
Mediawiki doesn't work that way. You can turn an image into a link only by adding a |link=
parameter to the file call. Since you can't add semantic markup to an image, you'd have to process that separately (probably using the {{#set}}
parser function so it happens invisibly). So to do what you want, it would look like this:
[[File:myIcon|link=theValue]] {{#set: myProp=theValue }}
