- The *text* attribute can be used to hold additional data associated with

+ These attributes can be used to hold additional data associated with
+ the element. Their values are usually strings but may be any
+ application-specific object. If the element is created from
+ an XML file, the *text* attribute holds either the text between

+ the *tail* attribute holds either the text between the element's
+ end tag and the next tag, or ``None``. For the XML data

- The *tail* attribute can be used to hold additional data associated with
- the element. This attribute is usually a string but may be any
- application-specific object. If the element is created from an XML file
- the attribute will contain any text found after the element's end tag and
- before the next tag.
+ the *a* element has ``None`` for both *text* and *tail* attributes,
+ the *b* element has *text* ``"1"`` and *tail* ``"4"``,
+ the *c* element has *text* ``"2"`` and *tail* ``None``,
+ and the *d* element has *text* ``None`` and *tail* ``"3"``.
+
+ To collect the inner text of an element, see :meth:`itertext`, for
+ example ``"".join(element.itertext())``.
+
+ Applications may store arbitrary objects in these attributes.
