xalan:indent-amount does not work in Translets

           Summary: xalan:indent-amount does not work in Translets
           Product: Xerces2-J
           Version: 2.6.0
          Platform: All
        OS/Version: Other
            Status: NEW
          Severity: Minor
          Priority: Other
         Component: Serialization
        AssignedTo: xerces-j-dev@xml.apache.org
        ReportedBy: alick.buckley@lansa.com.au


I have been using Xalan 2.4.1 for several years and have been planning to 
upgrade to 2.5.1, 2.5.2 or 2.6.0

What has delayed the upgrade is that the xalan:indent-amount is no working in 
translets for releases after 2.4.1.

<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:xalan="http://xml.apache.org/xslt">

<xsl:output method="xml" omit-xml-declaration="yes" indent="yes" xalan:indent-
amount="2" /> 

The xalan:indent-amount does not work when the style sheet has been compiled to 
a translet class.

Also the xalan namespaces are not removed, I have to include xalan in the 
exclude-result-prefixes attribute along with other namespaces.

I use the xsltc class to compile a style sheet into a translet class

	xsltc.compile ( inputStream, className )

Then I deploy the translet

I need to call the setIndentAmount to get indenting to work.
 
   handler.setIndentAmount ( 2 ) ;

The translet is not honouring the xalan:indent-amount attribute on the output.
