You can use any of the <A href="extensions.html#ext-func-calls">three namespace formats</A>

<P>The official namespace for the Java extension is <CODE><FONT face="courier, monospaced">http://xml.apache.org/xalan/java</FONT></CODE>. The old XSLTC Java namespace
<CODE><FONT face="courier, monospaced">http://xml.apache.org/xalan/xsltc/java</FONT></CODE> and the old Xalan-Java namespace <CODE><FONT face="courier, monospaced">http://xml.apache.org/xslt/java</FONT></CODE>
are also supported for backward compatibility.</P>
<P>All usage syntax for the Xalan-Java Interpretive processor also applies to XSLTC with only one
exception: XSLTC does not support the notion of default object
in <A href="extensions.html#ext-func-calls">class format namespace</A>.
When using instance methods, you should always specify the class instance as the first argument
to the extension function.</P>
<P>The following example shows you how to call constructors, static, and nonstatic functions,
using different namespace formats:</P>

module are implemented natively in XSLTC. For all other EXSLT extension functions,
XSLTC uses the same implementation as the Xalan-Java Interpretive processor. The implementation classes
are under <CODE><FONT face="courier, monospaced">org.apache.xalan.lib</FONT></CODE>.
Depending on the packaging, these classes can be in a separate jar file (e.g. xalan.jar) from
the XSLTC classes. In this case you need to add the jar file containing the EXSLT classes to your
classpath in order to use EXSLT extensions in XSLTC.</P>

<P>XSLTC supports the output extension element for redirecting the output to one
or more files. The output extension element is also aliased to the write extension element
in the namespace <CODE><FONT face="courier, monospaced">http://xml.apache.org/xalan/redirect</FONT></CODE>. Therefore you can use
it in the same way as the <A href="extensionslib.html#redirect">redirect</A>
extension in Xalan-Java.</P>
<P>You can use the file and append attributes with the output/redirect extension. The value of the file
attribute is an attribute value template. If the value of the append attribute is true or yes, the
output is appended to the file rather than overwriting the file.</P>
