undeclared namespace ?

Hello xsl-list,

How does namespace work?

File.xml transformed with StyleSheet1:
Gives Error:
xml transformation failed due the following error
Reference to undeclared namespace prefix: 'str'.


Stylesheet1 includes Stylesheet2 includes StyleSheet3

If I drop str: from  <xsl:call-template name="str:change-case"> (StyleSheet1) and
the the named template in StyleSheet3. Then it all works fine?




--------------
StyleSheet1    Has include for StyleSheet2

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
                        xmlns:fo="http://www.w3.org/1999/XSL/Format">

<xsl:include href="util_vb6.xsl" />
<xsl:output method="text" />

<!-- Main entry point. -->
<xsl:template match="/">

   <xsl:call-template name="str:change-case">
      <xsl:with-param name="value" select="'KP'"/>
   </xsl:call-template>
...

-----------------
StyleSheet2:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:include  href="D:\Seipas\OOSAD\DBDesign4\StyleSheets\util-strings.xsl" />
...

-----------------
StlyeSheet3:  Note namespace xmlns:str

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
         xmlns:str="http://www.seipas.com/namespaces/strings" 
         extension-element-prefixes="str">

<!--util-strings.xsl-->
<!--Utility for string-handling functionality.-->

<!-- Change case -->
<xsl:template name="str:change-case">
   <xsl:param name="value"/>
   <xsl:param name="case" select="'lower'"/>
      <xsl:choose>
         <xsl:when test="$case='lower'">
            <xsl:value-of select="translate($value,'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz') "/>
         </xsl:when>
         <xsl:when test="$case='upper'">
            <xsl:value-of select="translate($value,  'abcdefghijklmnopqrstuvwxyz', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ')"/>
         </xsl:when>
         <xsl:otherwise>
             <!--Incorrect change-to passed in. So just return the original string--> 
            <xsl:value-of select="$value"/>
         </xsl:otherwise>
      </xsl:choose>
</xsl:template>
