Here's a key to the markup:
	[page-number]: serious technical mistake
	{page-number}: minor technical mistake
	<page-number>: important language/formatting problem
	(page-number): language change or minor formatting problem
	?page-number?: reader question or request for clarification



Confirmed errors:


(back cover)  towards the bottom;
"DJ Adams is the author of sabber..."

should be

"DJ Adams is the author of sjabber..."


(Appendix A)  various places;
Lots of markup conversion errors; there are many instances of

&sol;

which should simply be

/


For example:

<default&sol;>

on page 431 should be, of course:

<default/>


(63)  last para;
"The conditions are OR'ed together--f any of the conditions..."

should be

"The conditions are OR'ed together--if any of the conditions..."



(71)  2nd Paragraph;
section "Server vCard
should be:
section "Server vCard"



{127}  para starting "This is where the concept of...";
"(priority values must be a positive integer and cannot be 0 or less)"

should be

"(priority values must be integers, and cannot be less than 0)"


(140)  first para of the "to" section;
"...in which case the JID will be in the form hostname> with an optional..."

should be

"...in which case the JID will be in the form hostname with an optional..."


{164}  XML following para beginning "For an IQ-set...";
<vCard xmlns='vcard-temp' version='3.0'>

should be

<vCard xmlns='vcard-temp' version='2.0'>


(196)  para starting "The format...";
"The format of the <tz/> and <display> tags..."
should be
"The format of the <tz/> and <display/> tags..."


(203)  XML in example 6-7;
<x xmlns='jabber:x:expire' seconds='600' stored='993038415'/>

should be

<x xmlns='jabber:x:expire' seconds='1800' stored='993038415'/>


{205}  Ex 6-8;
<vCard xmlns='vcard-temp' version='3.0'>

should be

<vCard xmlns='vcard-temp' version='2.0'>


{209}  the XML;
<vCard xmlns='vcard-temp' version='3.0'>

should be

<vCard xmlns='vcard-temp' version='2.0'>


{329}  Ex.9-17;
The code listing is missing the first few lines (they appear correctly
in the step-by-step breakdown starting on p333). The missing first few
lines are these:

use strict;
use Jabber::Connection;
use Jabber::NodeFactory;
use Jabber::NS qw(:all);
use MLDBM 'DB_File';
use LWP::Simple;
use XML::RSS;


(366)  last para;
The second sentence "One of the functions..." would really benefit from a rewrite,
especially as it's potentially a bit confusing and difficult to follow the flow with
all the examples, figures and sidebars in this area.

May I humbly suggest the sentence starting "One of the functions.." be replaced with
this:

"What information is returned depends on what information is stored
in the JUD in the first place. You can find out what fields are available for
population by sending an IQ-get in the jabber:iq:register namespace, as shown in
Example 10-3."


{369}  the XML;
<VCARD version="3.0" xmlns="vcard-temp">

should be

<VCARD version="2.0" xmlns="vcard-temp">
