XSTL: match xmlns

Hello people!
This is my first post of the year and I want to start with something which was driving me crazy for 2 days in a row.
I have a XML which I want to transform into another format by using XSTL:
Input XML <?xml version='1.0' encoding='UTF-8'?> <POSServices xmlns = "http://pos.odc.vzwcorp.com" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation = "http://pos.odc.vzwcorp.com http://pos.odc.vzwcorp.com"> <ServiceHeader> <userName>motrn1</userName> <password>*******</password> <clientAppName>DVS</clientAppName> <clientAppUserName>VZW-ACSS</clientAppUserName> <serviceName>MISC</serviceName> <serviceAction>CMELIGIBILITY</serviceAction> <applicationResponseCode>NOT_SET</applicationResponseCode> <applicationResponseClass>NOT_SET</applicationResponseClass> <applicationResponseMessage>NOT_SET</applicationResponseMessage> <applicationResponseDetails>NOT_SET</applicationResponseDetails> <timeStamp>2011-01-10T10:21:38</timeStamp> <storeID/> <clientAddlInfo>NETA</clientAddlInfo> <transactionId/> <sessionID/> <serviceAreaZip>00000</serviceAreaZip> <responseFormat>XML</responseFormat> </ServiceHeader> <ServiceBody> <cmEligibilityCheck> <response> <mtn>2022078155</mtn> <eligibility>N</eligibility> </response> </cmEligibilityCheck> </ServiceBody> </POSServices>
If you look carefuly to my input XML, there is something new: <POSServices xmlns = "http://pos.odc.vzwcorp.com" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation = "http://pos.odc.vzwcorp.com http://pos.odc.vzwcorp.com">
This kind of tag requires some special extra work, because if XML'd come without these extra stuff, like this: <POSServices> My work'd be really easy :D
To solve this issue I have to add these extra information on my stylesheet:

xmlns:n="http://pos.odc.vzwcorp.com" exclude-result-prefixes="n"

Why "n"? Because I wanted :P, I could be using juan, pedro, etc.
Then on my XPath expressions I have to include my prefix on each tag I'm looking for: n:POSServices, n:ServiceBody/n:cmEligibilityCheck/n:response/n:mtn
my XSTL <?xml version="1.0" encoding="UTF-8" ?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:n="http://pos.odc.vzwcorp.com" exclude-result-prefixes="n"> <xsl:output method="xml" indent="yes" /> <xsl:template match="n:POSServices"> <service> <serviceHeader> <billingSys>VZW-POS</billingSys> <clientId><xsl:value-of select="n:ServiceHeader/n:clientAppUserName"/></clientId> <serviceName>posCampaignManagerElegibility</serviceName> <userId><xsl:value-of select="n:ServiceHeader/n:clientAppUserName"/></userId> <password/> <statusCode>00</statusCode> <errorCode><xsl:value-of select="n:ServiceHeader/n:applicationResponseCode"/></errorCode> <errorMsg><xsl:value-of select="n:ServiceHeader/n:applicationResponseMessage"/></errorMsg> </serviceHeader> <serviceBody> <serviceResponse> <mtn><xsl:value-of select="n:ServiceBody/n:cmEligibilityCheck/n:response/n:mtn"/></mtn> <earlyUpgradeIndicator><xsl:value-of select="n:ServiceBody/n:cmEligibilityCheck/n:response/n:eligibility"/></earlyUpgradeIndicator> </serviceResponse> </serviceBody> </service> </xsl:template> </xsl:stylesheet>
And finally what you'll get is what you're expecting ;)
Output XML <?xml version="1.0" encoding="UTF-8"?> <service> <serviceHeader> <billingSys>VZW-POS</billingSys> <clientId>VZW-ACSS</clientId> <serviceName>posCampaignManagerElegibility</serviceName> <userId>VZW-ACSS</userId> <password/> <statusCode>00</statusCode> <errorCode>NOT_SET</errorCode> <errorMsg>NOT_SET</errorMsg> </serviceHeader> <serviceBody> <serviceResponse> <mtn>2022078155</mtn> <earlyUpgradeIndicator>N</earlyUpgradeIndicator> </serviceResponse> </serviceBody> </service>
