I was really surprised:
 Before I commited r22417, I run all make checks and got no errors.
 Yelp 3.2.1 had no problems to render the page
 Later I run xmllint manually and found 2 errors.

So I think, we should run xmllint -valid -noout on */*/gnucash-*.xml, if  make check or distcheck is called.

Any objections?

What is to do?

1. configure.in needs a section:
dnl
dnl Check for xmllint
dnl
AC_PATH_PROG(XMLLINT, xmllint)
if test -z "$XMLLINT"; then
  AC_MSG_ERROR([xmllint not found, perhaps you should install the libxml2 package ?])
fi

Note: according README this is no new dependency, but until now unchecked.
Question: Are there distries out with other naming conventions?
Nice Sideeffect: I compared configure.in with http://wiki.gnucash.org/wiki/Translation#Prerequisite and gnucash-docs/README and synced them [22422].

2. the makefile magic:
Here am I lost. I don't know, where to add the check and need some help.

PS: On the screen enter_bug.cgi I don't see a button, to assign the bug to myself. All the stuff below Description/Comment and Attachment is missing.
