This interface defines a method for checking whether a string is considered to be a valid URI.
<p>A user-supplied implementation of this class can be set in a customized instance of
<A HREF="../../../../net/sf/saxon/lib/ConversionRules.html" title="class in net.sf.saxon.lib"><CODE>ConversionRules</CODE></A>, which can be set in the configuration using
<A HREF="../../../../net/sf/saxon/Configuration.html#setConversionRules(net.sf.saxon.lib.ConversionRules)"><CODE>Configuration.setConversionRules(ConversionRules)</CODE></A></p>
<p>A user-supplied implementation can be written either from scratch, or by reference to the
system-supplied implementation <A HREF="../../../../net/sf/saxon/lib/StandardURIChecker.html" title="class in net.sf.saxon.lib"><CODE>StandardURIChecker</CODE></A>.

<DL>
<DD>Check whether a given string is considered valid according to the rules of the xs:anyURI type.
<p>This method is called during schema validation, and when casting string to xs:anyURI. It is not
used when the xs:anyURI type is used as a return value from methods such as namespace-uri() or
namespace-uri-from-QName() - in such cases no checking is applied to the name.</p>
