"PDF/A Metadata missing extension schema" during PDF/A conversion (LCES821SP2)

Issue

---

 The customer came across the following errors while converting documents onto PDF/A:

"PDF/A Metadata is missing extension schema."

"PDF/A Metadata is using an invalid prefix."

"PDF/A Metadata is using an undefined element."

Solution

---

 It turned out that I already came across this issue in the past. It was related to some custom meta data that LCES does not recognised.

This issue was solved by not only removing these custom metadata but also by removing some additionnal metadata.
