 * Old 'header' command is no longer supported (legacy since
 Isabelle2015).
 
+* Command 'bundle_definition' provides a local theory target to define a
+bundle from the body of specification commands (e.g. 'declare',
+'declaration', 'notation', 'lemmas', 'lemma').

+  \<^descr> \<^theory_text>\<open>bundle_definition b begin body end\<close> defines a bundle of declarations
+  from the \<open>body\<close> of local theory specifications. It may consist of commands
+  that are technically equivalent to \<^theory_text>\<open>declare\<close> or \<^theory_text>\<open>declaration\<close>, which also
+  includes \<^theory_text>\<open>notation\<close>, for example. Named fact declarations like ``\<^theory_text>\<open>lemmas a
+  [simp] = b\<close>'' or ``\<^theory_text>\<open>lemma a [simp]: B \<proof>\<close>'' are also admitted, but
+  the name bindings are not recorded in the bundle.
+
   \<^descr> \<^theory_text>\<open>print_bundles\<close> prints the named bundles that are available in the
   current context; the ``\<open>!\<close>'' option indicates extra verbosity.
