Check all schemes for unnecessary @minOccurs, @maxOccurs and @usage

Description

Clone of railML 2.4 ticket #344 (closed)

In railML schemes there are elements that occur exactly one time. Thus, @minOccurs="1" and @maxOccurs="1". Since these are default values, they don't have to be given explicitly. The same applies for @use="optional" for attributes.

Background

See #344 (closed)

Proposed solution

Before finalising railML 2.5, remove in all schema files:

• minOccurs="1"
• maxOccurs="1"
• use="optional"
