Missing documentation: Additional for describing Medieval manuscripts

[riedde]

These elements must be described/explained for the guidelines:

• [ ] <decoDesc/>
• [ ] <heraldry/>
• [ ] <rubric/>
• [ ] <sealDesc/>
• [ ] <secFolio/>
• [ ] <signatures/>

This should be checked with a medieval specialist

In today's meeting we agreed on asking other IGs for help, e.g., mensural and neumes
