- Any attribute not explicitly mentioned here does not support validation or content assist in this release. Most "pass-through" HTML values, as you can see, are not.
- "Boolean" type attributes are validated according to the JSP specification which uses Boolean.valueOf(StringValue). This means that seemingly invalid Strings as boolean evaluate to false. ex. "blue" means false
