4 Paragraphs

Emacs has several commands that operate on paragraphs, most notably M-q. nXML mode redefines these to work in a way that is useful for XML. The exact rules that are used to find the beginning and end of a paragraph are complicated; they are designed mainly to ensure that M-q does the right thing.

A paragraph consists of one or more complete, consecutive lines. A group of lines is not considered a paragraph unless it contains some non-whitespace characters between tags or inside comments. A blank line separates paragraphs. A single tag on a line by itself also separates paragraphs.
