To show a hint to the user when the field has the focus, use the COMMENT attribute.
If the field is mandatory for an input, combine the NOT NULL with the REQUIRED attribute.
The value accepted for the field can be limited with the INCLUDE attribute.
To provide a default value, define the DEFAULT attribute for the field.
Use the DOWNSHIFT or UPSHIFT attributes to force the letter case during input.
Input can be hidden (for example for password fields), with the INVISIBLE attribute.
Especially for mobile devices, use the KEYBOARDHINT attribute to get a specific keyboard when entering values into the field.
Input completion proposals can be implemented with the COMPLETER attribute.
