Mostly an SPI for creating project types centered around the Ant build tool.
Permits Ant-based project types to be registered and supplies various support
implementations to help satisfy the contract of <code>Project</code> and
various optional interfaces.

<answer id="arch-usecases">
<p>
Mostly an SPI for use by project type providers to create the project type.
Also includes a small API/SPI for other projects to find what Ant build steps
are necessary to create a certain build product, for use in inter-project
dependencies.

<b>Ant project support faq:</b>
<usecase id="support-for-storing-project-properties" name="How to use support for storing project properties?">
<em><b>Q:</b>
I'm creating a customizer (properties dialog) for my project type. I wan't to use the support
for simple data types. What do I need to do?</em>
<p>
You basicaly need to do two things. First create the representation of the project properties which
can be used in the GUI. Second at some time convert the objects back to the ANT properties form and
store them into the project.
</p>
<ul>
<li><b>Creating the object representation.</b>
<ol>
<li>Create new instance of StoreGroup for each group of properties you want to store later
e.g. project and prvate. Sometimes it might be useful to create temporary source group
which will only be used for creating the models without being used for storing. E.g.
for properties which need special handling.</li>
<li>Call the factory methods e.g. createBooleanButtonModel, createStringDocument, etc. which
will create the swing models for you.</li>
<li>Use the models in your Swing controls by calling setModel() or setDocument()</li>
</ol>
</li>
<li><b>Storing the models back to the proprties of project.</b>
<ol>
<li>Get the EditableProperties you want to store the model in e.g. private or project
properties</li>
<li>Call the store method on given SourceGroup with the EditableProperties as parameter</li>
<li>Manually store models which need some special handling.</li>
</ol>

A check for buggy Xalan is performed during startup. The test tries to lookup
