QtQuick anchoring syntax confusion

As we know, anchoring is done like this:

anchors.left: rect1.right

... where rect1 is an object deriving from Item.

But the Item QML type doesn't have a right property. So how does this anchoring syntax work?

See this and then this header file. anchors.left for example is a read-only property of type QQuickAnchorLine.
See this and this headers. There is where you can see how it works.

It does. The documentation for e.g. anchors.right links to Positioning with Anchors, which says:

In addition to the more traditional Grid, Row, and Column, Qt Quick also provides a way to layout items using the concept of anchors. Each item can be thought of as having a set of 7 invisible "anchor lines": left, horizontalCenter, right, top, verticalCenter, baseline, and bottom.

I'm not entirely certain why they're not documented like regular properties, though.
