The 'tspan' and 'a' element already have the transform property. It would be nice if textPath would also have it, to make all text element children behave similarly. The use cases are the same as for tspan: jiggling animations etc.

Currently, one has to resort to a wrapper a element:

<text>Hello <a transform="rotate(45)"><textPath path="..">rotated text on path</textPath></a> !!</text>
