+    This attribute delays target validation errors for internal attributes
+    from compile time to when the attribute is instantiated via the Reflection API.
+   </simpara>
+   <simpara>
+    When applied to a declaration, any invalid usage of internal attributes
+    on the same target will not trigger a compile time error. Instead, the
+    validation is deferred and performed when the attribute is accessed via
+    the Reflection API.
+   </simpara>
+   <simpara>
+    This is primarily intended for forward compatibility, allowing code to
+    use attributes that may gain additional valid targets in future PHP
+    versions without breaking on older versions.
