Description of problem:

"make test-en-US" and "make html-en-US" do not produce errors when the number of cells in a table is more than the value specified. Books build successfully in HTML. Errors occur when using "make pdf-en-US" and the book fails to build.

Version-Release number of selected component (if applicable):

* Red Hat Enterprise Linux Client release 5.2 (Tikanga)
* publican-0.37-0.el5
* saxon-6.5.5-1jpp.3.el5

How reproducible:

Always.

Steps to Reproduce:

Use the following table in a document, that specifies there are 3 columns (<tgroup cols="3">), when there are 6:

<table frame="all">
	<title>Example Table</title>
	<tgroup cols="3">
		
		<thead>
			<row>
				<entry>0</entry>
				<entry>1</entry>
				<entry>2</entry>
				<entry>3</entry>
				<entry>4</entry>
				<entry>5</entry>
			</row>
		</thead>
		
		<tbody>
			
			<row>
				<entry>data</entry>
				<entry>data</entry>
				<entry>data</entry>
				<entry>data</entry>
				<entry>data</entry>
                                <entry>data</entry>
			</row>
              </tbody>
		
	</tgroup>
</table>


Actual results:
"make test-en-US" = no errors.
"make html-en-US" = no errors; book builds.
"make pdf-en-US"  = errors; book fails to build.

Expected results:
"make test-en-US" = errors.
"make html-en-US" = errors; book fails to build.

Additional info:

The HTML and HTML-single outputs from a document with such a table are both XHTML 1.0 Strict according to <http://validator.w3.org/>.
