<rect width="150" height="150" fill="orange">
<animate attributeName="x" from="0" to="300"

Answer 1

It does, but may depends of browsers/devices, because YOUR code is INVALID: you can't put a html comment inside a tag ^^ which can have only attribute in it... Fortunaly, browser try to repair malformed documents, but don't ever succeed :P
