[Ur] HTML5 tags: source tag conflict

[Sergey Mironov]

Hi! I am working on adding HTML5 media tags to the basis. According to
the reference [1], <audio> tag may contain one or more tags named
<source>. Unfortunately, we already have value named 'source' in
basis.ur. What can we do to address this issue?  I'll try to
experiment with adding source tag via FFI for now and see how it looks
like.

Regards,
Sergey
