version 1.6.1 - data method will camelize data key if "-" is used

[justnewbee@…]

jQuery 1.6.1 if i call .data("x-y", someData) will not be able to find or remove the data using key "x-Y", because the data key is changed to "xY". However 1.4.2 works fine.

That behaviour is 100% correct per the data-* attr spec, also: see #7328

Look under "HTML 5 data- Attributes" here:  http://api.jquery.com/data

i don't think this is right, because in previous versions like 1.4.2, it's ok to use "-", at least this should be a compatibility bug. how do you explain .removeData("x-y") won't work but .data("x-y") can work? another thing, .data("x-X", someData) won't be changed according to HTML5 spec? i will complain about compatibility. it's wise to handle HMTL5 data-* attributes, but it's not wise to consider user set data the same format as HTML5, it's even worse .data("x-y") can work but .removeData("x-y") fails.

I'd like to open this particular issue for discussion. I see the point here. If xY can be accessed with x-y in the .data() method, I think it should be accessible in the .removeData() method as well so that things like this don't happen:

I've been working on a related ticket, so I'll take this and include it with that one.
