  * Supports display format that may differ from the input format.
  * Provides methods to increment and decrement any specific/targeted `DatePart`.
  *
+ * **Note:** This directive uses the Mask Directive internally and requires `type="text"` on the input element.
+ * Input elements with `type="date"` or other date/time types are not supported, as they do not allow
+ * programmatic cursor positioning and text selection required for mask functionality.
