[x3d-public] question re scripts and XML entities

[Yves Piguet]

X3D XML must be valid XML. So your question probably means "is it better to use cdata in X3D XML scripts or to escape special XML characters with entities?"

My feeling is that cdata is preferred for the sake of legibility. But if you generate xml programmatically, you should still detect and escape the sequence of three characters ]]> which marks the end of cdata, replacing it with something like (unquoted) "]]>]<![CDATA[]>".

I think general-purpose xml producers prefer entities. Also cdata blocks (and xml empty elements and case-sensitive tags and attribute names) aren't supported in html5, hence the difficulty to produce X3D XML embeddable in both xhtml and html.
