XML - some troubles

Hello,

suppose having:

---- t.xml

<a>
   <aa number="111">AA</aa>
   <ab>AB</ab>
</a>

----

and the Ctx source:

---- t.mkiv

\startxmlsetups xml:T
   \xmlsetsetup{\xmldocument}{*}{+}
   % \xmlsetsetup{\xmldocument}{*}{-} % Empties output?!
   \xmlsetsetup{\xmldocument}{a/ab}{xml:*}
\stopxmlsetups

\startxmlsetups xml:ab
   \section{New section \xmlatt{#1/../aa}{number}}
   \xmlflush{#1}
\stopxmlsetups

\xmlregistersetup{xml:T}

\starttext
   Hello

   \xmlprocessfile{id}{t.xml}{}
\stoptext

----

Some questions:

1)

Why the line "\xmlsetsetup{\xmldocument}{*}{-}" (try to uncomment!) causes the whole output is empty, even if I specify another operation for "a/ab" elements later?

My intention is to have "{*}{-}" (don't flush anything by default), excluding elements specified later, e.g. "a/ab" (with another operation specified);
how to achieve this?

2)

How to get "aa.number" from within "ab" element?

I believed "\xmlatt{#1/../aa}{number}" within "a/ab" will do that, but...? How to do that?

Thank you in advance;
I'm not very familiar with Ctx XML processing (so far)...

Best regards,

Lukas
