Sequences of elements changed in infrastructure from 3.1 to 3.2alpha

Description

The order of elements within sequences has changed in multiple sequences. Identified in infrastructure, rtm4railml3 and gml4railml3 schemas. Thomas is working on a list of all changed sequences per schema and will update the issue ASAP.

See #446 (closed) and #448 (closed) for similar previous issues.

Proposed solution in railML 3.2

For elements that already existed in railML 3.1, the order shall be the same in 3.2, and must be corrected where it has changed.
