R: xmllint error

[cri79 at libero.it]

HI David,
good to know you are tackling the learning curve on dockbook! Can you provide 
the xml file you have modified so that I can check myself what the error means?
I suspect you missed some proper tagging in the section you edited so you are 
getting the error. At first it is quite difficult to locate the problem but 
then with some experience you get better at finding errors.

Let me briefly explain how xml dockbook works: we have a "main" file called 
gnucash-guide.xml that contains all references to many other xml files (one for 
any chapter in the guide). That is why you are getting the error for gnucash-
guide.xml although you don't edited it. When you run xmllint, it expands the 
xml files creating virtually only one xml file.  The ":473" after "gnucash-
guide.xml" in the error message, means the error is on row 473 of the fully 
expanded document (in fact, the plain gnucash-guide.xml don't have so many 
lines).

Regards
Cristian
