+# XML EXCHANGE TABLE MODEL DECLARATION MODULE
+
+# This set of declarations defines the XML version of the Exchange
+# Table Model as of the date shown in the Formal Public Identifier
+# (FPI) for this entity.
+# 
+# This set of declarations may be referred to using a public external
+# entity declaration and reference as shown in the following three
+# lines:
+# 
+# <!ENTITY % calstblx
+#   PUBLIC "-//OASIS//DTD XML Exchange Table Model 19990315//EN">
+#   %calstblx;
+# 
+# If various parameter entities used within this set of declarations
+# are to be given non-default values, the appropriate declarations
+# should be given before calling in this package (i.e., before the
+# "%calstblx;" reference).
+
+# The motivation for this XML version of the Exchange Table Model
+# is simply to create an XML version of the SGML Exchange Table
+# Model. By design, no effort has been made to "improve" the model.
+# 
+# This XML version incorporates the logical bare minimum changes
+# necessary to make the Exchange Table Model a valid XML DTD.
+
+# The XML version of the Exchange Table Model differs from
+# the SGML version in the following ways:
+# 
+# The following parameter entities have been removed:
+# 
+#   - tbl.table.excep, tbl.hdft.excep, tbl.row.excep, tbl.entry.excep
+#     There are no exceptions in XML. The following normative statement
+#     is made in lieu of exceptions: the exchange table model explicitly
+#     forbids a table from occurring within another table. If the
+#     content model of an entry includes a table element, then this
+#     cannot be enforced by the DTD, but it is a deviation from the
+#     exchange table model to include a table within a table.
+# 
+#   - tbl.hdft.name, tbl.hdft.mdl, tbl.hdft.excep, tbl.hdft.att
+#     The motivation for these elements was to change the table
+#     header/footer elements. Since XML does not allow element declarations
+#     to contain name groups, and the exchange table model does not
+#     allow a table to contain footers, the continued presence of these
+#     attributes seems unnecessary.
+# 
+# The following parameter entity has been added:
+# 
+#   - tbl.thead.att
+#     This entity parameterizes the attributes on thead. It replaces
+#     the tbl.hdft.att parameter entity.
+# 
+# Other miscellaneous changes:
+# 
+#   - Tag ommission indicators have been removed
+#   - Comments have been removed from declarations
+#   - NUMBER attributes have been changed to NMTOKEN
+#   - NUTOKEN attributes have been to changed to NMTOKEN
+#   - Removed the grouping characters around the content model
+#     parameter entry for the 'entry' element. This is necessary
+#     so that an entry can contain #PCDATA and be defined as an
+#     optional, repeatable OR group beginning with #PCDATA.
+
+# This entity includes a set of element and attribute declarations
+# that partially defines the Exchange table model.  However, the model
+# is not well-defined without the accompanying natural language
+# description of the semantics (meanings) of these various elements,
+# attributes, and attribute values.  The semantic writeup, also available
+# from SGML Open, should be used in conjunction with this entity.
+
+# In order to use the Exchange table model, various parameter entity
+# declarations are required.  A brief description is as follows:
+# 
+# ENTITY NAME      WHERE USED              WHAT IT IS
