The SVG specification refers the reader to the XML Database Specification for characters that can appear in the value of the id attribute.
However, the XML database specification does not specify these characters, AFAICT. Instead, he makes his recommendations in terms of the "Unicode properties" of ID_Start and ID_Continue .
I am looking for a table (or table s ) that explicitly indicates those characters that have the ID_Start and / or ID_Continue .
(If various XML-based applications or standards can specify their own character sets using the ID_Start and / or ID_Continue , I'm interested in the SVG built into HTML5).
