[ACTION-153] related to [ISSUE-15] targetPointer

Hi all,

I have the action item to summarize the status of the targetPointer requirements
This related to ISSUE-15.

The current requirement (http://www.w3.org/International/multilingualweb/lt/wiki/Requirements#targetPointer) outlines several use cases.

I think the current status is:

- There is 3 intended implementations.

- It seems all questions about the reasons to have such feature have been answered in Dublin.

- The exact scope and model of the data category needs to be finalized.

So here is more thoughts to try to make this progress:

First, like for idValue, I believe now that this should be its own data category rather than an addition to the Translate data category: the feature should be available without using Translate.

As far as how to indicate the target, I think there is a distinction of what can be achieved depending on the way we set this up:

Shaun was illustrating his thoughts with:

 selector="//license[@xml:lang='en']" repeatable="yes"

To describe a case like this:

<application>
 <license xml:lang="en">
  <p>This is the license.</p>
  <p>It has multiple paragraphs.</p>
 </license>
 <license xml:lang="de">
  <p>Dies ist die Lizenz.</p>
  <p>Es verfügt über mehrere Absätze.</p>
 </license>
</application>

Such notation however:

 a) It would not work for cases where the target(s) are in non-sibling nodes.

 b) It would work only if the document uses xml:lang to distinguish the different language blocks (as it is the only implicit difference one can make in the example).

<application>
 <src>
  <license>
   <p>This is the license.</p>
   <p>It has multiple paragraphs.</p>
  </license>
 </src>
 <targets>
  <target langCode='1'>
   <license>
    <p>Dies ist die Lizenz.</p>
    <p>Es verfügt über mehrere Absätze.</p>
   </license>
  </target>
 </targets>
</application>

Or, more simply, for bilingual cases where the content is a single element:

<msgs>
 <m id='1'>
  <src>Text of the message</src>
  <trg>Texte du message</trg>
 </m>
</msgs>

So, I think an XPath relative expression would be more flexible because it would allow both use cases:

<its:targetPointerRule "//license[@xml:lang=$SourceLang]" targetPointer="../license[@xml:lang=$Target]"/>

<its:targetPointerRule "//src" targetPointer="../targets/target[@langCode=$TargetCode]"/>

However, this method has also a possible drawback: like with Shaun's example, with more complex expressions creating the target node if it does not exist, may be complicated. 

I wonder if then the data category scope could be limited to work, at least, with existing nodes?

Anyway, I hope you will have some additional ideas.
>From the experience we had with ITS 1.0 I know this is a feature that would be used.
