Answer Source

You are part of the way there, but you have made a few mistakes.

text-anchor="center" is wrong. It should be text-anchor="middle".

In addition, you should add startOffset="50%" to the <textPath> element to specify that the text should be centred on the half-way point of the path.

Finally you need to fix the path itself. You need to remove the Z path command at the end of the path description. You only want the arc, not the return line back to the start of the arc.
