[whatwg] What it means for attributes of input to apply or not apply
Hi, When adding[1] the placeholder= attribute to input type=number, one of our engineers asked me about the behavior of content attributes that don't apply to certain input types. Consider for example input type=range. The spec says[2] [t]he following content attributes *must not be specified* and *do not apply* to the element: […] placeholder[…] (emphasis mine). The first bit (must not be specified) is clear: it's an authoring conformance requirement. The second bit (does not apply to the element), however, isn't clear. Is it a UA conformance requirement? What does it mean? I *think* it means that the placeholder= attribute has no effect on the rendering of input type=range. Does it also mean that the placeholder= content attribute shouldn't be reflected as an IDL attribute on input elements of type=range? In Safari 5, Firefox 4, and Opera 11, placeholder= gets reflected as an IDL attribute, regardless of the value of type=.
