Missing and empty href in <a> from <ulink>

Using the the none-chunked docboox.xsl to transform into XHTML, a

<ulink url="http://sourceforge.net/">link</ulink>

yields

<a ="" target="_top">link</a>

Use the included build.xml to transform test.xml into test.html. The included test.html has already been reformated to simplify review of this bug.

In order to find the docbook-xsl stuff, make sure that it is a located in xml/docbook-xsl/xhtml/docbook.xsl, or modify the related

<xslt ... style="xml/docbook-xsl/xhtml/docbook.xsl">

in the build.html.

Ant should generated the following output:

----------
Buildfile: build.xml

init:

bug-missing-href:

The "Attribute xmlns must be declared" messages are already covered by [bug 1061942] (Spurious xmlns="" with Xerces/Xalan), but this one exposes the problem of my bug:

Element type "a" must be followed by either attribute specifications, ">" or "/>".

I'm using ant 1.6.1 from the fink distribution under MacOS 10.3.5.
