----------------------------------------------------------
If the configuration of a handler is as follows
{code:xml}
<requestHandler name="/foo" class="solr.FooHandler">
<defaults>
<name>some-name</name>
<classname>solr.MyClass</classname>
</defaults>
</requestHandler>
{code}
The values can be read from the iniArgs as follows
{code:java}
NamedList defaults = (NamedList )initArgs.get("default");
String name = (String)defaults.get("name");
String classname = (String)defaults.get("classname");
{code}
Even attributes can be read as in the following config
{code:xml}
<requestHandler name="/foo" class="solr.FooHandler">
<defaults name="default" name="somename" classname="solr.MyClass"/>
</requestHandler>
{code}
The values can be read from the iniArgs as follows
{code:java}
NamedList defaults = (NamedList )initArgs.get("default");
String name = (String)defaults.get("@name");
String classname = (String)defaults.get("@classname");
{code}

This patch can automatically make these representations equivalent. This is
fully backward compitible.
* NamedList format: 1
{code:xml}

> Project: Solr
> Issue Type: Improvement

> Reporter: Noble Paul
> Priority: Trivial
> Fix For: 1.3

> Attachments: SOLR-614.patch

>
> All the components initialized by Solr have an init(NamedList args)
> initializer. This leads us to writing the configuration needed for the
> component in the NamedList xml format. People familiar with Solr may know the
> format but most of what is written is noise than information. For users who
> are not familiar w/ the format find it too difficult to understand why they
> have to write it this way. Moreover , it is not a very efficient way to
> configure .
