<P>
This class implements the default collection URI Resolver.
<p>
This supports two implementations of collections. If the URI supplied uses the "file:/" scheme, and the
file that is referenced is a directory, then the collection is the set of files in that directory. Query parameters
may be included in the URI:
<ul>
<li><p>recurse=yes|no controls whether the directory is scanned recursively; </p></li>
<li><p>strip-space=yes|no determines whether whitespace text nodes are stripped from the selected documents; </p></li>
<li><p>validation=strict|lax|preserve|strip determines whether schema validation is applied;</p></li>
<li><p>select=pattern determines which files in the directory are selected.</p></li>
<li><p>on-error=fail|warn|ignore determines the action taken if processing of a file fails</p></li>
<li><p>parser=qualified.class.name selects the parser (XMLReader) to be used to read the files</p></li>
</ul>
<p>
Otherwise, the resolver attempts to dereference the URI to obtain a catalog file. This is an XML file
containing a list of documents, in the format: </p>
<pre>
<collection>
<doc href="doc1.xml"/>
<doc href="doc2.xml"/>
</collection>

was called with no arguments (to get the "default collection") this argument
will be null.<DD><CODE>base</CODE> - The base URI that should be used. This is the base URI of the

<DT><B>Returns:</B><DD>an Iterator over the documents in the collection. The items returned
by this iterator must be instances either of xs:anyURI, or of node() (specifically,
<A HREF="../../../../net/sf/saxon/om/NodeInfo.html" title="interface in net.sf.saxon.om"><CODE>NodeInfo</CODE></A>.). If xs:anyURI values are returned, the corresponding
document will be retrieved as if by a call to the doc() function: this means that
the system first checks to see if the document is already loaded, and if not, calls
the registered URIResolver to dereference the URI. This is the recommended approach
to ensure that the resulting collection is stable: however, it has the consequence
that the documents will by default remain in memory for the duration of the query
or transformation.
