Problem with "<link>" in xslt output

Hi!

Is <link> a reserved word in libxslt ?
(I don't see it listed in the xslt reference on zvon.org)

I have an xsl where the expected output is of the form 

<link>foo</link>

It worked with sablotron (php4) but after moving to libxslt (php5)

the output is just 

<link>

If i change the tag in the output to <linky> (or anything else) it works
fine and the output is in the expected form

<linky>foo</linky>

I tested it out with perl and found the same error... 

You can see the snipped out xml/xsl files and php and perl code which
demonstrates the unexpected output at http://kingsly.net/tmp/xsltbug.tgz
