[4436]13``tld2xsc`` is a script that converts a JSP Tag Library Descriptor XML file
14into a skeleton XIST namespace module. The tld file is read from stdin and
15the namespace module is printed to stdout.
[4436]17``tld2xsc`` supports the following options:
[4436]19    ``-s``, ``--shareattrs`` : ``none``, ``dupes``, ``all``
20        Should attributes be shared among the elements? ``none`` means that each
21        element will have its own standalone :class:`Attrs` class directly derived
22        from :class:`ll.xist.Elements.Attrs`. For ``dupes`` each attribute that is
23        used by more than one element will be moved into its own :class:`Attrs`
24        class. For ``all`` this will be done for all attributes.
26    ``-m``, ``--model`` : ``no``, ``simple``, ``fullall``, ``fullonce``
27        Add model information to the namespace. ``no`` doesn't add any model
28        information. ``simple`` only adds ``model = False`` or ``model = True``
29        (i.e. only the information whether the element must be empty or not).
30        ``fullall`` adds a :mod:`ll.xist.sims` model object to each element class.
31        ``fullonce`` adds full model information to, but reuses model objects for
32        elements which have the same model.
