You probaly run into default templates. The problem is here:

> <FirstStream><xsl:apply-templates select="stream1"/>
               ^^^^^^^^^^^^^^^^^^^^^^^^^
You tell the processor to recursively apply templates.
The processor looks for matching templates, and if there
aren't any, it falls back to the default template, which
simply applies templates to child nodes. It ultimately
copies text nodes, but wont copy elements or attributes.

If you want to have a literal copy of the subtree, use
xsl:copy-of instead of xsl:apply-templates:

 <xsl:template match="overall">
   <FirstStream>
     <xsl:copy-of select="stream1"/>
   </FirstStream>
   <SecondStream>
     <xsl:copy-of select="stream2|stream3"/>
   <SecondStream>
 </xsl:template>
This is also very fast.

If you have some other templates you want kick in on elements
deeper down the tree, add a generic copy-through template to
your style sheet:
 <xsl:template match="node()|@*">
    <xsl:copy>
       <xsl:apply-template select="node()|@*"/>
    </xsl:copy>
 </xsl:template>
This template matches everything and will therefore be used
rather than falling back to the default templates.
