What is the `edit` attr in a meta tag - 【StackMirror】|html|meta-tags

I was looking at jsfiddle's code and saw these lines:

<meta name="description" edit="mootools shell, easy test you snippets before implementing">
<meta name="keywords" edit="mootools,javascript,javascript framework,shell,test">
<meta name="robots" edit="all">

I've never seen the edit attr before. What does it do? I couldn't find any info on w3.org or google

Perhaps it is invalid html? You can pretty much put anything into html, the browsers won't complain. I think they might be using it to provide some data for the js. That is all just a wild speculation though - d_inevitable 2012-04-03 21:08

Ok I guess I am right then, thanks @RepWhoringPeeHa - d_inevitable 2012-04-03 21:11

I would bet it's just mistake on their part and the "edit" attribute should have been "content". Maybe you should send them a note and let them know.

Update: I just sent Piotr a note, letting him about it. I'll update my answer with his response (if any).

Yeah those should both be content attributes - Wesley Murch 2012-04-03 22:05

The robots tag actually invalid since "all" isn't a valid option even if content attribute was used. I asked Piotr about it as well - BluesRockAddict 2012-04-03 22:07

@BluesRockAddict: Who's that - qwertymk 2012-04-03 22:15

He's the person behind jsfiddle: http://piotr.zalewa.info - BluesRockAddict 2012-04-03 22:17

Any update on the attr - qwertymk 2012-04-10 02:31

I've received no response from Piotr, so I guess we won't know for sure (or maybe meta tags get fixed eventually) - BluesRockAddict 2012-04-10 04:50

The edit attribute is not valid html:

 Line 4, Column 33: there is no attribute "edit"
  <meta name="description" edit="mootools shell, easy test you snippets before …
✉

So this means that it is either used by jsfiddle itself to pass values onto their js, or by some web-crawlers that I do not know of.

I have checked google's crawler, but it doesn't mention any such attributes.

I kind of doubt they're using something like easy test you snippets in an attribute as a javascript hook for jsfiddle itself... looks more like a mistake - Wesley Murch 2012-04-03 22:06
