Hi all,

I've just put together a patch for the JDepend task to use xml output. A new
attribute "format" has been added that can take either "xml" or "text"
defaulting to the latter.  Appropriate changes have been made to the
documentation, and additionally a .xsl file is attached to produce html with
a similar style to that of junitreport.

Testing:
I haven't produced a testcase xml file as I couldn't think of a decent test
to perform.  Instead I have manually tested it using Ant 1.5a, Win2000,
JDepend 2.1, and the Xalan 2.2.D11 for the xsl.

Hope people find this useful,

Rob

	<h3><a name=3D"EXnumber">Number of Classes</a></h3>
		<p>The number of concrete and abstract classes (and interfaces) in the =
package is an indicator of the extensibility of the package.</p>
	<h3><a name=3D"EXafferent">Afferent Couplings</a></h3>
		<p>The number of other packages that depend upon classes within the =
package is an indicator of the package's responsibility. </p>
	<h3><a name=3D"EXefferent">Efferent Couplings</a></h3>
		<p>The number of other packages that the classes in the package depend =
upon is an indicator of the package's independence. </p>
	<h3><a name=3D"EXabstractness">Abstractness</a></h3>=20
		<p>The ratio of the number of abstract classes (and interfaces) in the =
analyzed package to the total number of classes in the analyzed package. =
</p>
		<p>The range for this metric is 0 to 1, with A=3D0 indicating a =
completely concrete package and A=3D1 indicating a completely abstract =
package. </p>
	<h3><a name=3D"EXinstability">Instability</a></h3>
		<p>The ratio of efferent coupling (Ce) to total coupling (Ce / (Ce + =
Ca)). This metric is an indicator of the package's resilience to change. =
</p>
		<p>The range for this metric is 0 to 1, with I=3D0 indicating a =
completely stable package and I=3D1 indicating a completely instable =
package. </p>
	<h3><a name=3D"EXdistance">Distance</a></h3>
		<p>The perpendicular distance of a package from the idealized line A + =
I =3D 1. This metric is an indicator of the package's balance between =
abstractness and stability. </p>
		<p>A package squarely on the main sequence is optimally balanced with =
respect to its abstractness and stability. Ideal packages are either =
completely abstract and stable (x=3D0, y=3D1) or completely concrete and =
instable (x=3D1, y=3D0). </p>
		<p>The range for this metric is 0 to 1, with D=3D0 indicating a =
package that is coincident with the main sequence and D=3D1 indicating a =
package that is as far from the main sequence as possible. </p>
