Subject:		invalid bytes are the worst problem

The worst (most likely) problem with embedding binary data directly in XML is that not all bytes are allowed in XML. The standard limits the valid characters to: #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] So, for example, with utf-8 encoding, the byte value 1 is not allowed. CDATA sections are no help at all in this case.
