Detailed conversion changes

Summarise all steps to be applied to the element / attribute in question: changes in the tag name, context and availability, sub-elements to be removed or added (in case of new mandatory sub-elements), attributes (with their values, if applicable and of importance for the conversion path) to be removed or added (in case of new mandatory attributes).
Summary of changes:

• Move <repositories> out of <desc> and add it to <eag> instead
• Add <repository> as a parallel element to <repositories> in <eag>
  • In <eag>, there will be a choice between either one (not repeatable) <repository> or a <repositories> wrapper element including at least two <repository> sub-elements
• Move sub-elements of <repository> into <desc>
• Move <desc> and <identity> out of <archguide> and into <repository>
  • Rename <desc> to <description> in this context
• Remove <archguide>

Example

Provide an example snippet of the current element (with all relevant sub-elements and attributes) and the expected conversion result.
