In general it is quite good, but it doesn't give you control
over formatting.  For example, it outputs 3 spaces as an
indent.  What if I thought 2 spaces were adequate?  I cannot
control it.  What if I wanted double newlines after certain
elements?  The list goes on, but this isn't Saxon's fault.
The XSLT specification doesn't provide for this level of
control throught the use of the indent="yes" attribute.

However, that doesn't mean that you cannot control indenting
yourself.  It is a pain in the neck, but it can be done.  Use
indent="no" and output the appropriate whitespace whereever
you want it.

<xsl:variable name="indent"  select="string('&#20;&#20;')"/>
<xsl:variable name="newline" select="string('&#10;')"/>

<xsl:value-of select="concat($newline,$indent)"/>
<xsl:element name="foo">
  <xsl:value-of select="concat($newline,$newline,$indent,$indent)"/>
  <xsl:element name="bar">
    <xsl:value-of select="concat($newline,$indent,$indent)"/>
  </xsl:element>
  <xsl:value-of select="concat($newline,$newline,$indent)"/>
</xsl:element>

Should produce:

  <foo>

    <bar>
    </bar>

  </foo>

Ugly, especially for deeply nested structure, but it works.
