Description
When loading vector data in INTERLIS 2 format (.xtf) and the first record is missing an attribute value (because it is optional according to the corresponding model (.ili)), no source field is generated in QGIS for this attribute.
For all subsequent records which have a corresponding attribute value in the data, this value is not available in QGIS.
Steps to reproduce:
1. Load attached file attribute_available.xtf into QGIS as a new layer.
2. Open Attribute Table of the created layer and recognize field named Breite.
3. Load attached file attribute_not_available.xtf into QGIS as a new layer.
4. Open Attribute Table of the created layer and recognize that the field named Breite is missing.
The only difference between the two datasets (which can be viewed with a text editor) is the order of the two records (line 5 and 6). In attribute_available the first record contains an XML tag <Breite> where as in the other file <Breite> is missing in the first record.

It is messing also using OGRINFO, so this is a OGR bug, agree?

I agree. I'm going to open an issue at https://github.com/OSGeo/gdal then.
Thanks
