Allows access to all custom data attributes (data-*) set on this element.
The keys for the map must follow these rules:
- The name must not begin with 'xml'.
- The name cannot contain a semi-colon (';').
- The name cannot contain any capital letters.
Any keys from markup will be converted to camel-cased keys in the map.
For example, HTML specified as:
<div data-my-random-value='value'></div>
Would be accessed in Dart as:
var value = element.dataset['myRandomValue'];
