<p>When out on the lawn there arose such a clatter,</p>
<p>I sprang from the bed to see what was the matter.</p>
<p>Away to the window I flew like a flash,</p>
<p>Tore open the shutters, and threw up the sash.</p>
<p>The moon on the breast of the new-fallen snow</p>
<p>Gave the lustre of mid-day to objects below,</p>
<p>When, what to my wondering eyes should appear,</p>
<p>But a miniature sleigh, and eight tiny rein-deer,</p>

<p>With a little old driver, so lively and quick,</p>
<p>I knew in a moment it must be St. Nick.</p>
<p>More rapid than eagles his coursers they came,</p>
<p>And he whistled, and shouted, and called them by name;</p>

<p>As dry leaves that before the wild hurricane fly,</p>

<p>So up to the house-top the coursers they flew,</p>
<p>With the sleigh full of toys, and St. Nicholas too.</p>

<p>And then, in a twinkling, I heard on the roof</p>
<p>The prancing and pawing of each little hoof.</p>
<p>As I drew in my hand, and was turning around,</p>
<p>Down the chimney St. Nicholas came with a bound.</p>

<p>He was dressed all in fur, from his head to his foot,</p>
<p>And his clothes were all tarnished with ashes and soot;</p>
<p>A bundle of toys he had flung on his back,</p>
<p>And he looked like a peddler just opening his pack.</p>
<p>His eyes -- how they twinkled! his dimples how merry!</p>
<p>His cheeks were like roses, his nose like a cherry!</p>
<p>His droll little mouth was drawn up like a bow,</p>
<p>And the beard of his chin was as white as the snow;</p>
<p>The stump of a pipe he held tight in his teeth,</p>
<p>And the smoke it encircled his head like a wreath;</p>
<p>He had a broad face and a little round belly,</p>
<p>That shook, when he laughed, like a bowlful of jelly.</p>
<p>He was chubby and plump, a right jolly old elf,</p>
<p>And I laughed when I saw him in spite of myself;</p>

<section1 topic='References' anchor='refs'>
<p>The foregoing poem, informally known as <cite>'Twas the Night Before Christmas</cite> but formally entitled <cite>Account of a Visit from St. Nicholas</cite>, was authored by Major Henry Livingston Jr. in 1807 or 1808. <note>As noted at &lt;<link url='http://rpo.library.utoronto.ca/poem/1312.html'>http://rpo.library.utoronto.ca/poem/1312.html</link>&gt;, "In the year 2000, Don Foster, an English professor at Vassar College in Poughkeepsie, New York, used external and internal evidence to show that Clement Clarke Moore could not have been the author of this poem, but that it was probably the work of Livingston, and that Moore had written another, and almost forgotten, Christmas piece, <cite>Old Santeclaus</cite>. Foster's analysis of this deception appears in his <cite>Author Unknown: On the Trail of Anonymous</cite> (New York: Henry Holt, 2000): 221-75." See also &lt;<link url='http://rpo.library.utoronto.ca/poet/204.html'>http://rpo.library.utoronto.ca/poet/204.html</link>&gt; and &lt;<link url='http://www.henrylivingston.com'>http://www.henrylivingston.com/</link>&gt;.</note></p>

<p>This document assumes the following architecture:</p>
<code><![CDATA[

| |-- cupid
| (occupants) |-- donder
| |-- blitzen
|-- santa et al.
]]></code>
<p>In addition, we assume that the twas-the-night.lit server is running a virtual pubsub service for each account it hosts (in accordance with <cite>XEP-0163</cite>) and that the users "narrator", "mama", and "child" publish information to personal pubsub nodes related to mood (<cite>XEP-0107</cite>), activity (<cite>XEP-0108</cite>), and physical location (<cite>XEP-0112</cite>).</p>
<p>* The U.S. Military divides its operations geographically among NORTHCOM, SOUTHCOM, EUCOM, and PACOM. Given the scale of operations implemented by Santa's workshop, it comes as no surprise that the command center at the North Pole is known as POLECOM. Naturally POLECOM subscribes to the pubsub feeds for Santa's geolocation and activity, as well as the sleigh's geolocation, just in case a search and rescue mission needs to be initiated.</p>

<section1 topic='Internationalization Considerations' anchor='i18n'>
<p>The protagonist of this poem is variously called (in English) St. Nicholas, St. Nick, Santa Claus, Kris Kringle, and bears a striking resemblance to the Sinterklaas of Dutch legend. Use of the name "St. Nicholas" is not meant to disparage other names for this character in English or any other language.</p>
