When I first started trying to learn SGML I developed a system (costwish)
which UUENCODED gifs and other binaries into a single. Since I have no
experience of SGML in practice I don't know whether that is the normal
thing to do.
When I came across something like the following:

I converted all the & to & and the < to <
I'm not clear why this isn't a useful method since the processor is
required to convert them on reading.
I have a problem to know what to do with "save XML" on JUMBO. In the
SAXDemo routine characters(), DavidM converts non printing chars to escaped
variants *e.g. asc(10) -> , but does *not* convert & to & This
means that any XML file that contains & will produce invalid XML output.
What is the appropriate strategy? Should a "save XML" application convert
all five chars (&, <, >, ', ") to their escaped equivalents? Or none? Or
just the first two. [In my own community I don't think using <![CDATA[ is a
good idea because people won't have any idea what is going on and they will
get it wrong. In any case - as pointed out - it doesn't overcome the
random occurrence of ']]>' ].
