Hum, it would be better to accept the same language as XML Schemas Datatype
would for interoperability and implementation reasons.
  I will note that:
   http://www.w3.org/TR/xmlschema-2/#base64Binary
doesn't define itself a lexical representation but reference RFC 2045,
so I think it would be simpler if no extraneous rule be applied there
(i.e. stick to rfc2045 and not mandate some of the more restrictive rfc2049
set of rules.)

  W.r.t. the stream of byte included, again it would be nice if the same
rules as for XInclude parse="text" were used, i.e. it does not enforce
normalization, it default to UTF8 encoding and allows the encoding to
be specified on the xinclude element. The xInclude processor then check
the encoding of the stream of bytes on import (and that they are within
the Char range defined by the XML Rec), see 
    http://www.w3.org/TR/xinclude/#text-included-items
for the full set of rules for parse="text".
