Yep, that too. "dm2_register_form_name_input" for example. You could probably mix upper/lowercase to format it better but for some reason I don't like to mix them, just personal preference.

I avoid dashes because the text editor I use doesn't select them as a whole word when I double click them.

Oops, I didn't mean to type "orderLine" in camel case. I usually use underscores in the entity and attribute names, and separate them with a dash, like "order_line-item_sku". That way, I can distinctly select the entity or attribute, or easily search for all attributes for a given entity, like "order_line-".
