What version of Go are you using?

go1.7.3

What operating system and processor architecture are you using?

linux/amd64

What did you do?

I'm working on an HTML sanitizer, where I want to access the original escaped HTML attribute values during the parse.

What did you expect to see?

An ideal solution to me would be a flag in the Tokenizer which could indicate if unescaping is required or not when calling TagAttr().
If you find this useful, i can implement it, or if you have any better idea, please reply.

What did you see instead?

As I see, currently the only option is Tokenizer.TagAttr() which automatically unescapes attribute values: https://github.com/golang/net/blob/master/html/token.go#L1158 .
Escaping again the unescaped attribute values can be a solution, but that re-escaping adds computational and structural complexity to the program what I want to avoid if possible.

thanks,
