[TYPO3-templavoila] FCE and availibility of fields (10.file.width.field = field_width)

[Matthew Colton]

Hi,
I'm trying to figure something out: How can I access an unmapped value across 
containers. It seems the "field" attribute only has a local scope, i.e. it 
only works within the same container. I' talking about something like:

10.file.width.field = field_width

Take the following DS as an example that doesn't work:

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<T3DataStructure>
  <meta type="array">
    <langDisable>1</langDisable>

      <description>Select the HTML element on the page which you want to be 
the overall container element for the template.</description>

    <type>array</type>
    <el type="array">
      <field_container type="array">

My problem is, that the line "10.file.width.field = field_width" won't work. I 
posted that to Typo3-english, where Dmitry Dulepov politely pointed out that 
I was posting to the wrong group. 
And he also answered: 'If you want to map field to the attribute, you need to 
set field type as "attribute", not "element". Currently in your DS it 
is "element".'
Well first of all, I don't get what he's saying because I think he 
misunderstood my problem, second of all I've done this before and it worked 
and third of all I found out (by trial an error) that my mistake was the fact 
that I tryed to get a field which was not in the same container/scope. The 
following works DS like a charm:

  </ROOT>
</T3DataStructure>

Is there some way to get a field from a global scope as I tried in DS listing 
1? The basic idea is to have a free amount of different image types (normal, 
linked and click-enlarge) and be able to set the scaling for ALL elements at 
once. The examples above are simplified, there is only one image type 
(normal).
Listing 2 works but you have to set the scaling per image which has an 
overhead.

Thanks in advance!
