Dan Vint has
produced an interactive reference to the
EBNF productions from XML specifications.
The reference documents several XML specifications,
including XML 1.0, Namespaces, XPath, XSLT,
and XPointer. Via a file/folder-like interface, the user
can locate productions from the
specifications, which are extensively hyperlinked.
Also included are descriptions of each symbol and
validation constraints. In a message to XML-DEV, the author requested
feedback and suggestions for the site.
