Release notes

This file describes all the important changes introduced to the schema after its initial 1.0.0 release.

Please note, that all changes in the v1 branch will be backward-compatible.

Version 1.1.0

We have found a bug in version 1.0.0 of the schema - it allowed for only a single <description> element to be present (per LOS). This version allows for an unbounded number of such elements.

Since disallowing multiple descriptions was just a mishap, and we believe all the clients will still expect multiple descriptions present, we have chosen to treat this change as backward-compatible, and not increase the major version of the schema yet.
Added a new value to the attachment type enumeration: EMREX transcript. See the XSD for the description of this new value.
The previous version of the schema required for all ELMO files to include additional XSDs whenever the <extension> element was used. This limitation was dropped - all <extension> elements will now pass the validation (they still need to have an appropriate xmlns attribute though!).
It was unclear which ISCED type should be used in the <iscedCode> element. The description of the element has been made more explicit to clear this matter.
Updated the example.xml file to better reflect the changes made to the XSD.
Minor changes to the "Status of this document", "Backward-compatibility policy" and "Schema versioning" sections of the XSD documentation. They don't change the overall meaning of the previously accepted contents.

Initial release of the schema.
