This is a late reply, but to clarify, the only target attribute value that has any effect in a single browser window is _blank, which refers to a new tab or window. These are legacy attributes that apply to frameset, a very uncommon thing in today’s era now that we have CSS. Frames predated CSS.
Also of note, attributes have no order. They can be written in any order, though usually we like to see the id and class attributes out front, and in that order. That’s just for reading, though. The browser makes no distinction of ordering or attributes.
