This issue is related to documentation which is offered by https://dfg-viewer.de/, but not part of the GitHub repository.

While reading the documentation, I noticed a number of issues and inconsistencies.

Example:

In SRU-ALTO-Anwendungsprofil_1.0.pdf there is a mismatch between the description for dv:page (3 attributes: id, width, height) and the example (4 attributes: id, width, height, url). And there are typos like Elememente and several more.

It would be nice to have a repository for the documentation where issues and pull requests can be contributed.
