+# Bytes Without Data
+
+Each object `<o/>` in [XMIR], with its base containing `org.eolang.bytes` must
+have text data inside.
+
+Incorrect:
+
+```xml
+<program>
+  <objects>
+    <o name="bar" base="foo"/>
+  </objects>
+</program>
+```
+
+Correct:
+
+```xml
+<program>
+  <objects>
+    <o name="bar" base="foo">
+      A1-B2-C3-D4-E5
+    </o>
+  </objects>
+</program>
+```
