The begin, end, and empty-element tags that delimit the elements are correctly nested, with none missing and none overlapping; A single "root" element contains all the other elements; These features resemble those of trees, in that there is a single root node, and an order to the elements. XML has appeared as a first-class data type in other ...
We assume in the next points that the root element is at the first level, i.e., 0. Example of Min-max heap. Each node in a min-max heap has a data member (usually called key) whose value is used to determine the order of the node in the min-max heap. The root element is the smallest element in the min-max heap.
There is a single "root" element that contains all the other elements.

Form, link and image elements could be referenced with a hierarchical name that began with the root document object. A hierarchical name could make use of either the names or the sequential index of the traversed elements.
