+
+    .NOTES
+        If either of these flags are set, the template is considered published:
+
+        - CT_FLAG_IS_CA      (0x1): This bit indicates whether the template is for a Certification Authority (CA). If this bit is set, the template is considered published.
+        - CT_FLAG_IS_DEFAULT (0x2): This bit indicates whether the template is a default template. If this bit is set, the template is also considered published.
+
+        If pkiEnrollmentFlag has 0x10 (CT_FLAG_PUBLISH_TO_DS) set, the certificate is published to Active Directory.
