Standards are written for that: to ensure consistent behavior across multiple

There are a lot of features that have never been used, but they're still
This one should not be dropped because it allows to write image maps that are

<area href="examplemuseum" shape="circle" coords="375,375,20" alt="Example

<area href="examplemuseum-mapview" shape="rect" coords="350,350,50,50" alt="123
