Description:
Dr. Olaf Hoffmann <http://lists.w3.org/Archives/Public/www-svg/2008Sep/0089.html>: [[ elements like image, audio, video have a 'type' attribute. This attribute is not animatable and as far as I understand the data type <content-type> it can only represent one type. Because xlink:href of those elements is animatable, the content type can be time dependent. 'type' does not care about this problem and if authors want to give a hint, this is not possible with 'type' for those animations. 'typeof' (5.10.1) can both contain more than one type and is animatable, therefore this solves the problem, but then the 'type' is redundant and could be skipped. If 'typeof' is intended for something different (for example in some programming languages there is a typeof operator available with another meaning, the word 'datatype' may indicate something like this, but a content type still may be a specific data type, therefore this usage seems not to be excluded), then the problem of type and animation remains and it is not obvious, what the purpose of 'typeof' could be - the 'type' problem needs to be solved and 'typeof' needs a better description about the purpose of this attribute to avoid confusion with 'type'. ]]
