<!DOCTYPE PERSONS "http://www.w3.org/schemas/persons">
<PERSONS>

<!--
	The default attributes are used to make sure every record has
	the same number of attributes, even though they may be empty.
-->

<?xml default person
	first=""
	last=""
	street=""
	city=""
?>

<!--
	This is the start of the table. Each PERSON tag is a record in
	the table. Whitespace inside tags is ignored, so this can be
	prettyprinted at will. Between the tags, however, only
	newlines are ignored, and only those that immediately follow a
	`>' or that immediate precede a `<'
-->

<PERSON
	first	= "John"
	last	= "Johnson"
	street	= "26, First Street"
	city	= "Bean&#39;s town"
/>
<PERSON
	first	= "Anne"
	last	= "Apple"
	street	= "12, Garden's Avenue"
	city	= "Greenwich"
/>
</PERSONS>

This document relies on attributes only. There is no content between the tags. The empty lines are ignored by the parser, because of the rule that a newlines before < or after > is ignored.

The declaration of default attributes is lexically scoped by the PERSONS element (although in this case it has no effect, since none of the elements omit an attribute).
