+=====================
+Report QWeb Parameter
+=====================
+
+This module allows you to add new parameters on QWeb reports.
+Currently, we have defined a field maximum on a report and a validation of
+maximal and minimal size.
+It is useful on xml reports in order to validate length.
+XML are sometimes XSD dependant and we must validate its format.
+For example, in spanish facturae (http://www.facturae.gob.es/Paginas/Index.aspx), where
+length and format must be validated in several fields in order to send an invoice.
+
+
+Usage
+=====
+
+#. Add a t-length attribute on report templates fields that will truncate the field
+#. Add a t-minlength attribute on report template fields that will check the min length
+#. Add a t-maxlength attribute on report template fields that will check the max length
