-## Question
+For significant change list, and open-issues see the [issues page in the build](http://build.fhir.org/ig/IHE/ITI.mXDE/branches/master/issues.html)
 
-- Why does mXDE need to add the mXDE actor to ITI-43? Seems it can just integrate the Document Consumer actor. What is wrong with mXDE requiring a grouping with Document Consumer? This would also seem to meet MHD vs XDS vs XCA need. Is the reason that one deployment model wants to decompose the documents upon publication rather than being triggered by a QEDm query?

 - [mXDE_001](https://github.com/IHE/ITI.mXDE/issues/1): There is no "Transform Considerations" identified in mXDE, but should there be? Such as preserving original identifiers in the resulting FHIR Resources, even when those identifiers can't be used to retrieve the original data, as they are still useful for de-duplication downstream.
+- [mXDE_003](https://github.com/IHE/ITI.mXDE/issues/3) nXDE_003: Use of Document Consumer grouping. The original mXDE chose not to group with Document Consumer, but rather chose to add the mXDE actor to the ITI-43 (Retrieve Document Set) transaction. I recommend we change to grouping with Document Consumer (possibly Content Consumer) to enable broader support such as MHDS and XCA.
