Some things wouldn't be converted correctly

[xitara]

email-fields become
"tag":"email", not "tag": "input"

file-upload fields missing "type": "file"

hidden-fields have not "type": "hidden"

submit-fields become "className": "..." in attr{} and options{} but in attr{} it's wrong

checkboxes and radios not displayed:
"attrs": {
"type": "radio|checkbox",
}
is missing

[xitara]

on hidden fields, "hideLabel": true will not be set
