5 An \<open>O_Model\<close> holds \<open>O\<close>riginal data, \<open>descriptor\<close> and \<open>values\<close> parsed from \<open>Formalise.model\<close>
6 selected with respect to a \<open>Model_Pattern\<close> and combined with respective \<open>m_field\<close>s.
7 \<open>complete_for\<close> a \<open>Model_Pattern\<close> is done by \<open>Tactic.Model_Problem\<close>
8 (with defaults from \<open>Formalise\<close>refs), by \<open>Tactic.Specify_Problem\<close> and \<open>Tactic.Specify_Method\<close>
10 \<open>O_Model\<close> serves efficiency of student's interactive modelling via \<open>I_Model\<close>.
12 \<open>O_Model\<close> marks elements with \<open>m_field\<close> \<open>#undef\<close>, which are not required by the \<open>Model_Pattern\<close>
13 of the \<open>Problem\<close> or the \<open>MethodC\<close> .. TODO redes: \<open>m_field\<close> probably different in root..Subproblem
15 TODO: revise with an example with more than 1 variant.
16 + consider: drop m_field ?
