"-" in tag name - PROBLEM with XALAN

[Saigal, Ankur]

Hi All,
I am an XSL which looks like this,

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:MB="urn:sap.com:CRM-Middleware:MapBox" version="1.0">
<xsl:template match="/">
<xsl:element name="MB:Root">
       <xsl:copy-of select="//MB:RECEPIENTS/"/>
       <xsl:element name = "MB:MESSAGE">
               <xsl:element name="tchunk">
                  <xsl:attribute name="name">BUPA</xsl:attribute>
                  <xsl:element name="row">
                        <xsl:attribute name="s">I</xsl:attribute>
                        <xsl:attribute name="NAME"><xsl:value-of
select="//CAPGEN_OBJECT/-1CRMG0_-CAPGEN_OBJECT01/NAME1/"/></xsl:attribute> 
                        <xsl:attribute name="CUSTNO"><xsl:value-of
select="//CAPGEN_OBJECT/-1CRMG0_-CAPGEN_OBJECT01/KUNNR/"/></xsl:attribute> 
                        <xsl:attribute name="STREET"><xsl:value-of
select="//BPADDRESS_OBJECT/_-1CRMG0_-BPADDRESS_OBJECT01/STREET/"/></xsl:attr
ibute> 
                        <xsl:attribute name="ZIPCODE"><xsl:value-of
select="//BPADDRESS_OBJECT/_-1CRMG0_-BPADDRESS_OBJECT01/POST_CODE1/"/></xsl:
attribute> 
                        <xsl:attribute name="CITY"><xsl:value-of
select="//BPADDRESS_OBJECT/_-1CRMG0_-BPADDRESS_OBJECT01/CITY1/"/></xsl:attri
bute> 
                        <xsl:attribute name="PHONE"><xsl:value-of
select="//BPPHONE_OBJECT/_-1CRMG0_-BPPHONE_OBJECT01/TEL_NUMBER/"/></xsl:attr
ibute> 
                        <xsl:attribute name="FAX"><xsl:value-of
select="//BPFAX_OBJECT/_-1CRMG0_-BPFAX_OBJECT01/FAX_NUMBER/"/></xsl:attribut
e> 
                 </xsl:element>
              </xsl:element> 
     </xsl:element>
</xsl:element>          
</xsl:template>
<xsl:template name="CAPGEN_OBJECT">

</xsl:transform>


While processing this XALAN gives me an error, saying "
javax.xml.transform.TransformerConfigurationException:
1CRMG0_-CAPGEN_OBJECT01 could not be formatted to a number! "
This means that it takes the "-" sign before this as substraction operator
and tries to convert 1CRMG0_-CAPGEN_OBJECT01 into a number.
To my understanding, the specification says that "-" shuould be considered
substraction operand only when it is succeeded by a space.
Is there any solution to this problem, some work around?

Thanks and Regards,
Ankur
