Terminology

The DOM [=nodes|node=] or [=element=] for which the text alternative is sought.
Current node
The DOM [=nodes|node=] currently traversed to compute the root node's text equivalent. Initially, the current node is the root node, but at later stages is either some descendant of the root node, or another referenced node.
+
Rendered child nodes
+
The [=nodes=] that are rendered as child nodes of a given node when taking [=shadow root|shadow roots=] and [=slot|slots=] into consideration.
Flat string
A string of characters where all carriage returns, newlines, tabs, and form-feeds are replaced with a single space, and multiple spaces are reduced to a single space. The string contains only character data; it does not contain any markup.
