Merge two messages into one file

[[EMAIL PROTECTED]]

I have some kind of requirement that I did not find answer from the
document.  May someone help me.

I have different message objects which are inherited from one parent.
I need to serialize the objects into one file.
Some kind of solutions like:
e.g.
 message Style {
        optional int32 color = 3;
        optional int32 size = 4;
}

message Text {
        optional Style style = 3;
        optional string context = 4;
 }

message Image {
        optional Style style = 3;

        optional int32 width = 4;
        optional int32 height = 5;
        optional bytes data = 6;
 }

My Group object includes Text objects and Image objects.  But the
position is not fixed.
e.g.                    Text.Image.Image...Text
and could be:     Image.Text...Image...Text

Now I need to serialize the objects into one file, and seek for the
solution using protocol buffer.
Implement this in Java is quite easy, because I can use
DataInputStream and serialize the objects.
Thanks for any hints.
