Several of the following term definitions have been borrowed or modified from similar definitions in other W3C or standards documents. See the links within the definitions for more information.

document element
There is only one document element in a Document. This element node is a child of the Document node. See Well-Formed XML Documents in XML [XML 1.0].
document order
There is an ordering, document order, defined on all the nodes in the document corresponding to the order in which the first character of the XML representation of each node occurs in the XML representation of the document after expansion of general entities. Thus, the document element node will be the first node. Element nodes occur before their children. Thus, document order orders element nodes in order of the occurrence of their start-tag in the XML (after expansion of entities). The attribute nodes of an element occur after the element and before its children. The relative order of attribute nodes is implementation-dependent.
An event is the representation of some asynchronous occurrence (such as a mouse click on the presentation of the element, or the removal of child node from an element, or any of unthinkably many other possibilities) that gets associated with an event target.
event target
The object to which an event is targeted.
partially valid
A node in a DOM tree is partially valid if it is well formed (this part is for comments and processing instructions) and its immediate children are those expected by the content model. The node may be missing trailing required children yet still be considered partially valid.
target node
The target node is the node representing the event target to which an event is targeted using the DOM event flow defined in [DOM Level 3 Events].
The description given to various information items (for example, attribute values of various types, but not including the StringType CDATA) after having been processed by the XML processor. The process includes stripping leading and trailing white space, and replacing multiple space characters by one. See the definition of tokenized type.
A node is a well-formed XML node if it matches its respective production in [XML 1.0], meets all well-formedness constraints related to the production, if the entities which are referenced within the node are also well-formed. See also the definition for well-formed XML documents in [XML 1.0].
