AWS textract documentation change
Summary
Simplified explanations of IAM policy elements (Action, Resource, Condition) by removing redundant details and consolidating content. Removed specific examples of policy evaluation logic (AND/OR conditions) and placeholder variables.
Security assessment
The changes are editorial improvements to streamline IAM policy documentation. While IAM policies are security-related, there is no evidence these changes address a specific vulnerability, incident, or weakness. The removals (e.g., NotResource mention, condition evaluation logic) clarify rather than fix security flaws. No new security features or explicit guidance are added.
