Metadata plugin and value quoting?

Metadata plugin and value quoting?

Hi guys!

I wanted to use metadata plugin and even the simplest examples I came up with wouldn't work. Then I realized that it needs double quotes, for example: <p data-key="'value'"></p>, otherwise it doesn't work.

Why is this so, and will this be fixed? I glanced over HTML5 specs, and it doesn't say that data- attributes have to be double quoted.

Thanks...
