+ *  DIGIT+ (&quot;.&quot; DIGIT+)*
+ *  - The mod-spec lacks a sep between *attrval-spec and &quot;-&quot;.
+ *  - The BASE64-UTF8-STRING should be BASE64-CHAR BASE64-STRING
+ *  - The ValueSpec rule must accept multilines values. In this case, we have a LF followed by a 
+ *  single space before the continued value.
