Section Sign § Valid in XML?

[AdAve]

Is the section sign (§) valid in XML?
Anyone know of a list of characters that are not valid in XML?
Thanks

Valid where in XML? Various characters are valid in various places. For the basic characters allowed list, see <uri:http://www.w3.org/TR/REC-xml/#charsets>.

However, if you're speaking about characters allowed in tags, in attribute names etc. that is further limited. (Though not much...)
