     XSD Schema
********************

Generating XSD Schema
=====================

You can use :ref:`compiler` to generate XSD schema from the set of Igor files using the following command:

.. code-block:: batch

   igorc.exe -xsd *.igor

This command will generate ``schema.xsd`` file in the current folder. You can override file name with ``-output-file``
command line option. See more information on available command line options here: :ref:`cli_options`.

XSD Schema Attributes
=====================

See :ref:`xml_attributes` for the list of XML related attributes.

Here's the additional list of attributes that affect XSD Schema generation.
