+ - The name must not start with
xml (case-insensitive).
+ - The name must not contain any colon characters (
:).
+ - The name must not contain any capital letters.
Note that the {{domxref("HTMLElement.dataset")}} property is a {{domxref("DOMStringMap")}}, and the name of the custom data attribute data-test-value will be accessible via HTMLElement.dataset.testValue (or by HTMLElement.dataset["testValue"]) as any dash (U+002D) is replaced by the capitalization of the next letter, converting the name to camelcase.
