Handle.hasSub

Checks whether the element id exists in the SVG document.

Element IDs should look like an URL fragment identifier; for example, pass #foo (hash foo) to get the geometry of the element that has an id="foo" attribute.

An element's id within the SVG, starting with "#" (a single hash character), for example, #layer1. This notation corresponds to a URL's fragment ID.
