  Version 1.0 is publically located at http://ns.inria.fr/limsee3/limsee3-1_0.dtd

  Change log from version 1.0
  ===========================
  * version 1.01: in the list of attributes of the 'ref' element, the line
                  refId            CDATA  #REQUIRED
                  is replaced by an equivalent entity
                  %id.ref;

  * version 1.02: the 'fit' attribute is renamed to 'smil:fit' to comply with a rather
                  mysterious SMIL choice - I mean all region attributes come without
                  a prefix EXCEPT fit.

  * version 1.03: version 1.02 is an implementation pain. We change the definition of the
                  'fit' attribute by adding into our preamble:
                  <!ENTITY % SMIL.fit.attrib "
                     fit  (hidden|fill|meet|meetBest|scroll|slice)   #IMPLIED
                  ">
                  Thus 'fit' has no more prefix in any element.
                  We update the expansion of %SMIL.region-attrs and ATTLIST smil:region
                  in the comments accordingly to this.

  * version 1.04: in fact, version 1.03 fixed only one of many problems with spurious prefixing
                  of attributes imported from SMIL. Now we use a far more general mechanism
                  that removes inconditionally all prefixes from all SMIL-defined attributes.
                  The "smil:" prefix is however maintained on SMIL elements.
                  So now, all attributes, be they SMIL-imported or LimSee3-defined, are without
                  any kind of prefix.

  * version 1.1:  added a 'regPoint' and 'regAlign' attributes into the layout element,
                  as well as a new regPoint element, which can be defined in a layout.
                  Since the the DTD becomes strictly more expressive with this addendum,
                  we start a new version series (v 1.1).

  * version 1.2:  switched to a new namespace for limsee3 (and for templates)

  * version 1.3:  changed the structure of text object, to allow areas
