Same name and namespace in other branches

1. 6 token.module \token_element_validate_token_context()
2. 7 token.module \token_element_validate_token_context()

Validate a form element that should have tokens in it.

Form elements that want to add this validation should have the #token_types parameter defined.

For example:

$form['my_node_text_element'] = array(
  '#type' => 'textfield',
  '#title' => t('Some text to token-ize that has a node context.'),
  '#default_value' => 'The title of this node is [node:title].',
  '#validate' => array(
    'token_element_validate_token_context' => array(),
  ),
  '#token_types' => array(
    'node',
  ),
);
