           Summary: XslCompiledTransform doesn't preserve xsl:text

If you Load a Xsl transform via XslCompiledTransform.Load using one of the
XmlReader overloads, xsl:text elements that contain only whitespace do not
cause the whitespace to appear in the output.  XslTransform does not have this

I'll be attaching a proposed patch with a test case included.  All I changed
was to have XslCompiledTransform.Load create the XPathDocument with the
XmlSpace.Preserve tag in the same way that XslTransform.Load does.  Here's a
test (which will also be in the patch file):

public void XslTextElement_PreservesWhitespace ()
        XslCompiledTransform xslt = new XslCompiledTransform ();
        xslt.Load (new XmlTextReader (new StringReader (@"
  <xsl:output method='text' omit-xml-declaration='yes'/>
  <xsl:template match='foo'>
    <xsl:text> </xsl:text>
        StringWriter sw = new StringWriter ();
        xslt.Transform (new XmlTextReader (new StringReader
(@"<foo>bar</foo>")), null, sw);
        Assert.AreEqual (" ", sw.ToString ());
