A topic fails the structure check

A count of headings, tables, rows, list items, code blocks or images differs between the two pages.

Cause: An element converted to a different structure, for example a table that became a list.

1. Read which count differs and by how much.
2. Find the element in the source that produces that structure.
3. Approve or write a mapping rule that rewrites it into DITA the converter handles.
