XML Schema does not support descending on columns in index

Description

In 3.4 "descending" was added as an attribute on column, and we use it successfully.
But when we upgraded to 3.5 we got a validation error. The "descending" attribute is removed from the schema.
Is this by design? Does 3.5 not support descending indexes anymore?

Environment

Affects all platforms since it's a schema problem
