Tim Bray wrote a relaxng schema which (IMHO) overcomes this quite
nicely. I write my main necho stuff in the twingly ns, then switch to
xhtml and write that, in xml,
http://www.tbray.org/ongoing/pie/0.1/pie.rnc
Removes the need to either escape or use cdata sections.
I thought it rather neat.
Content = element content
{
XMLbasics, attribute type { text },
( ( attribute mode { "xml" }?, XHTML )
| ( attribute mode { "escaped" | "base64" }, text)
| ( attribute src { xsd:anyURI } )
)
}
XHTML = element xh:*
{
attribute * { text }*,
( text | XHTML)*
}
