Support for PostCSS (parent-selector)

[alecandido]

Not even VSCode has support for PostCSS in the main CSS plugin (nor they intend to add, looks like, even though they later did something and refined it, but only for @-rules).

But there are available plugins that would support PostCSS (like PostCSS Language Support), so is it possible to wrap also them?

In particular, I would like to have support for sass-like parent selector.
If it is too complicate to wrap another plugin, would it be too complicated to add support for this rule?

Sorry, that's too much detailed for duplicated item... #8

Let's simply say: is there a specific way to remove that error, without removing validation all together?
