I would like to perform an XSL transformation over placeholder's content and their inner function calls, how can I do that?

Answer:

Firstly, you should create an xslt function, that accepts an "XElement" argument, you can use the following one, as a template:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	xmlns:in="http://www.composite.net/ns/transformation/input/1.0"
	xmlns:x="http://www.w3.org/1999/xhtml" 	
	xmlns="http://www.w3.org/1999/xhtml"
	exclude-result-prefixes="xsl in">
	
	<xsl:variable name="root" select="/in:inputs/in:param[@name='XHTML']/x:html"/>

	<xsl:template match="/">
	   <xsl:variable name="xhtml" select="/in:inputs/in:param[@name='XHTML']" />
	   
	   <html>
			<head>
				<xsl:copy-of select="$root/x:head"/>
			</head>
			
			<body>
			   <xsl:copy-of select="$root/x:body"/>
			</body>
	   </html>
   
	</xsl:template>
			   
	<xsl:template match="@* | node()">
		<xsl:copy>
			<xsl:apply-templates select="@* | node()" />
		</xsl:copy>
	</xsl:template>
	
	<!-- Put your transformation templates here -->			   
</xsl:stylesheet>

NOTE: In the example the function has a parameter named "XHTML" with the type of "XElement"

The next step - is to change the layout:

<f:function name="Composite.Example.Layout" xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://www.composite.net/ns/function/1.0" xmlns:rendering="http://www.composite.net/ns/rendering/1.0">
  <f:param name="XHTML">
  
  <!-- Layout content -->
 <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://www.composite.net/ns/function/1.0" xmlns:lang="http://www.composite.net/ns/localization/1.0" xmlns:rendering="http://www.composite.net/ns/rendering/1.0" xmlns:asp="http://www.composite.net/ns/asp.net/controls">
	<head>
	  <!-- ... -->
	</head>
	<body>
		<!-- ... -->
	</body>
  </html>
 
  </f:param>
</f:function>
