If you include or import a transform which has a func:function element, it 
incorrectly throws a TransformerException "func:function element must be
top level."

Basically if I take a function block and put it in my main stylesheet, it works 
fine, if I move it directly into an include, it fails as suggested above.

You can reproduce the effect with the following:
source.xml
-------------------
<?xml version="1.0"?>
<doc>
  <section index="section1" index2="atr2val">
    <section index="subSection1.1">
      <p>Hello</p>
      <p>Hello again.</p>
    </section>
  </section>
  <section index="section2">
    <p>Hello2</p>
    <section index="subSection2.1">
      <p>Hello</p>
      <p>Hello again.</p>
    </section>
    <section index="subSection2.2">
      <p>Hello</p>
      <p>Hello again.</p>
    </section>
    <p>Hello2 again.</p>
    <section index="subSection2.3">
      <p>Hello</p>
      <p>Hello again.</p>
    </section>
  </section>
</doc>
