OutputURIResolver Cause: net.sf.saxon.trans

Hi the list members,
Can anyone give me some insights to troubleshoot the problem as indicated below?

When compiling a set of XSLT version 1.0/1.1 style sheets using SAXON
9, I encountered with error as follows :
Exception thrown by OutputURIResolver Cause:: Resolved URL is malformed

Before which a number of other errors had been surpressed and one of
which in question is explained below:

To help you get more background information, the other errors
suppressed and resolutions are described as follows:

First problem:
Fatal error [xslt]
D:\InfoShare\App\Utilities\DITA-OT\SEMC_InfoShare\xsl\InfoShare\common\infoshare.filesystem.xsl:133:
Fatal Error! There is more than one method matching the function call
file:new, and there is insufficient type information to determine
which one should be used
Solutions:
I attempted the following in line with your post entitled Test if an
(image) file exists at
http://www.oxygenxml.com/archives/xsl-list/200506/msg00400.html

modified the problematic XSL either by
From: <xsl:value-of select="file:exists(file:new($filename))"/>

To: <xsl:value-of select="file:exists(file:new($filename as xs:string))"/>

Or change the line 132
From:
<xsl:param name="filename"/>
To:
<xsl:param name=" filename as xs:string "/>

But the above solutions did not come through, which led me to disable
all calls to the named template file-exists. This affects a number of
different XSLs.

The second problem and its solution:
@herf attribute is not allowed in Document() ; Changed all occurrence
of document (@href, ) to result-document(@href, ).
In case the switch from document() to result-document() is
problematic, please could you advise how to fix the error that @href
is not allowed in Document()? in the XSL where the exact problem was
complained about, its version reads ' <xsl:stylesheet version="1.1"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">'.

The Third problem and its solution:
XHTML namespace is not declared in transform.title.xsl Solution : Declared it.
