I'm trying to discern if the attribute syntax characters ( quoted key/value pairs ) are valid within html comments :
I can't tell if this is valid. I looked at:
It appears that they probably are -- except for a few references to "control characters". I can't find a definition for control characters in the spec.
The spec only requires:
- comment open "
- text
- comment close "-->"
Most browsers and parsers support having a quoted k/v pair in a comment. I've ran into a few issues with various open source libraries that can sometimes choke.
