/**
*
* Escapes an unquoted HTML attribute, or converts an array of such
* attributes to a quoted-and-escaped attribute string.
*
* When converting associative array of HTML attributes to an escaped
* attribute string, keys are attribute names, and values are attribute
* values. A value of boolean true indicates a minimized attribute. For
* example, `['disabled' => 'disabled']` results in `disabled="disabled"`,
* but `['disabled' => true]` results in `disabled`. Values of `false` or
* `null` will omit the attribute from output. Array values will be
* concatenated and space-separated before escaping.
*
* @param mixed $raw The attribute (or array of attributes) to escaped.
*
* @return string The escapted attribute string.
