Describe the Bug

It seems that the IDs on the symbol elements that are being generated are not valid XML according to the W3C markup generator. I am getting an error Bad value ai:local:services/screen for attribute id on element symbol: Not a valid XML 1.0 name for every icon that I include in my page. I guess this is due to the / inside the IDs?

What's the expected result?

I would expect valid IDs.
