------------------------------
5.7.4 ittm:altText - Optionality of attributes
------------------------------
For the XML Representation you may repeat the part from 2.3 TTML 1 where
it states that bold-face attribute names are required and the others are
optional (personally I would prefer the keyword "REQUIRED" after the
attribute name). Without that it may not be clear if the attributes are
optional or required.


------------------------------
5.7.4 ittm:altText - Typo
------------------------------
End of "Note:": Replace ". ." with "."
