The variables in scope for the function body include all variables representing the function parameters, as well as all variables that are in scope for the inline function expression.

Note:  Function parameter names can mask variables that would otherwise be in scope for the function body.

"custom-defined functions get no context item, position, or size, they have access to lexically scoped variables

<klotz> RESOLUTION: Custom-defined functions get no context item, position, or size, they have access to lexically scoped variables.

<function signature="my:f(p as number, q as number) as number" select="$p+$q"/>

<function name="my:foo" as="number">

<param name="p" as="number"/>

<param name="q" as="number"/>

<sequence select="$p + $q"/>

</function>

<function signature="my:f() as number" value="$context-pos = $context-size"/>

<klotz> value="concat('abc', ""'"''")"

<klotz> <function signature="my:f() as number">$context-pos = $context-size</>

<klotz> <function> ... whatever xpath 3 says </>

xpath 3.0: function() as xs:integer+ { 2, 3, 5, 7, 11, 13 }

<klotz> <function signature="my:f(name as string) as string" javascript="function sayHello2(name) {

<klotz> var text = 'Hello ' + name; // local variable

<klotz> var sayAlert = function() { alert(text); }

<klotz> return sayAlert;

<klotz> }" />

<function signature="my:foo(p as string)" as="number">

<script type="text/javascript">

foo(XForms.var.p);

</script>

</function>

<ebruchez> <function signature="my:f(name as string) as string" type="javascript" value="foo(XForms.var.p)"/>

<function name="my:sumproduct" as="number">

<param name="p" as="nodeset"/>

<sequence select="2*$p"/>

<sequence select="3*$p"/></function>

<function signature="my:sumproduct(p as number)" as="number">

  <sequence select="2*$p"/>

  <sequence select="3*$p"/></function>

<klotz> as="number*"

<ebruchez> <function>

<klotz> ACTION: Erik Bruchez to propose forward-compatible function body syntax for XPath 3. [recorded in http://www.w3.org/2012/03/14-forms-minutes.html#action01]

<trackbot> Created ACTION-1876 - Bruchez to propose forward-compatible function body syntax for XPath 3. [on Erik Bruchez - due 2012-03-21].

<function signature="my:foo(p as nodeset)" as="number" override="no">

<script type="text/javascript">

foo(XForms.var.p);

</script>

</function>

<function name="my:foo(p as nodeset)" as="number" override="no">

<sequence select="sum($p)"/>

</function>

Oh, I also added a script action

I hope the group isn't against this one
