I could be reading it wrong, but I don't think that section covers the behavior that I am seeing. The built-in template calls <xsl:apply-templates mode="m"/>, "which allows recursive processing to continue in the same mode". I wouldn't expect the built-in text() and attribute template to apply to every mode, at least I don't see that described in the spec...

I would expect this stylesheet:

<?xml version="1.0" ?>
<xsl:stylesheet version="1.0"
  xmlns:xsl=""; >
  <xsl:template match="/">
	<xsl:apply-templates mode="MISSING_MODE"/>

to output:


and not:

... all of the text nodes in the xml document ...

Both Xalan and Saxon behave as though there is a built-in text and attribute template that is equivalent to:

<xsl:template match="text()|@*" mode="m">
  <xsl:value-of select="."/>

There are defaults that apply to each mode, also, as described in the XSLT Rec, section 5.8:

There is also a built-in template rule for each mode, which allows recursive processing to continue in the same mode in the absence of a successful pattern match by an explicit template rule in the stylesheet. This template rule applies to both element nodes and the root node. The following shows the equivalent of the built-in template rule for mode m.

<xsl:template match="*|/" mode="m">
  <xsl:apply-templates mode="m"/>

I hope this fills it in for you --

It looks like the <xsl:apply-templates mode="g"/> at the bottom of the Global template is causing the default template to get invoked.

Adding a new empty template

  <xsl:template match="Global/text() | EVENT/text()" mode="g"/>

Will fixes the problem.

I'm not sure why the default template is being invoked in this case. I read both and and they seem to be saying that only templates with a matching mode will be invoked. The 

Can anyone explain why this is happening?

I am using XSL to generate another XSL file from an XML file. I am interested in only Element names and attributes but not it's values. for the following XML 

<Global param="A" name="Y">aaaaa</Global>
<Global type="if" name="A" select="abcd">bbbb</Global>
<Global type="when" name="Y" select="ccc" otherwise="bbbbb">ccccc</Global>

<EVENT spec="IDL:sciOmSiebelEvents/RouterToOmServer:1.0#OrderCopyEvent\">

I am getting the output as 

<xsl:stylesheet xmlns:xsl=""; version="1.0">
    <xsl:output method="xml" encoding="UTF-8" indent="yes"/>
    <xsl:preserve-space elements=""/>
    <xsl:strip-space elements="*"/>
    <xsl:param name="A"/>


<xsl:variable name="A">
        <xsl:value-of select="abcd"/>


<xsl:variable name="Y">
            <xsl:when test=" ">
                <xsl:value-of select=" ccc"/>
                <xsl:value-of select=" bbbbb"/>

 ccccc ddddd 

<xsl:template match="*"/>
    <xsl:template match="SiebelMessage"/>
    <!-- End of SiebelMessage -->

I am not sure why the element values are coming when i am not refering it them. Any suggestions are greatly appreciated..
