[whatwg] [html5] r5307 - [giow] (0) use vendor--feature instead of _vendor-feature since Apple engineers [...]

[Ian Hickson]

An update since this topic was discussed on this list before:

I updated the vendor-specific syntax a while back to be x-vendor-foo="" 
for content attributes, and .vendorFoo for IDL members; attributes 
starting with an underscore are also reserved but their use is not 
encouraged.

I don't know that we follow any concrete policy. HTML uses pretty much 
every naming convention you can come up with _somewhere_. When adding new 
features generally I just try to find an existing feature with a similar 
concept and then use the same naming scheme. So e.g. looking at recent 
additions, <bdo> suggests <bdi>, dir="" and name="" suggest dirname="".
