[xslt] Strange interaction between <xsl:text> and whitespace in XML outputmode



Given the following stylesheet


<?xml version="1.0" encoding="iso-8859-1"?>

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output encoding="iso-8859-1" indent="yes" 
doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" 
doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/>

<xsl:template match="/">

<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">

<head>
<title>Test</title>
</head>

<body>
<table>
<tr>
   <td>1</td>
   <td>2</td>
   <td>3</td>
</tr>
<tr>
   <xsl:text> </xsl:text>
   <td>4</td>
   <td>5</td>
   <td>6</td>
</tr>
</table>
</body>

</html>

</xsl:template>

</xsl:stylesheet>


and a dummy XML document with an empty root node, I get the following result


<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">
   <head>
     <meta http-equiv="Content-Type" content="text/html; 
charset=iso-8859-1" />
     <title>Test</title>
   </head>
   <body>
     <table>
       <tr>
         <td>1</td>
         <td>2</td>
         <td>3</td>
       </tr>
       <tr> <td>4</td><td>5</td><td>6</td></tr>
     </table>
   </body>
</html>


The <xsl:text> inside the second <tr> seems to disable the indented 
formatting. Apparently all whitespace is stripped inside elements that 
contain <xsl:text>.

This only happens in XML output mode. In HTML output mode (just use a 
<html>-element without attributes and adjust the doctype) the result is:


<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Test</title>
</head>
<body><table>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr> <td>4</td>
<td>5</td>
<td>6</td>
</tr>
</table></body>
</html>


Is this the expected behaviour? If yes, almost all elements in an XHTML 
result document will appear on one line which is still correct but 
completely unreadable.

I'm not on the list, please CC me.
