I have uploaded a version 1.1 of the OpenLR extension under the extension section. It resolvs remarks and bugs that has been discussed in this forum mainly.

An updated 1.0 version of the extension has also been uploaded. It was a misstake in the formar version, the UML model used was an unpublished post RC2 version.
The 1.0 version will stay published for some time because there are people using it. It's recommended to upgrade to the 1.1 version.
