Safe names for custom events

[scottgonzalez]

There are a lot of developers using custom events in their code. Right now there is no way to be sure that your custom event names will be safe to use in the future as more native events get added.

Specific Suggestions

• Create a prefix similar to data- attributes.
• Choose at least one character that will never appear in a native event so developers can include this somewhere in their custom event names. The form foo:bar seems to be somewhat popular.

I'm assuming this is solved on the CustomEvents api. Please re-open if not.
