As part of designing a digital publication open standard (OpenReader), we're now discussing the issue of allowed characters within URI attribute values in UTF-8 encoded XML documents. Reading XML 1.0 and RFC 3986, it is not at all clear (at least to me) what is allowed, or how much leeway exists. Specifically, when the attribute URI value includes non-ASCII characters (e.g., Greek characters), must these non-ASCII characters be percent-encoded in the attribute value (effectively "ascii-zing" the attribute value), or can the characters be kept natively encoded in the attribute value per the text encoding of the document? I guess this issue comes under the moniker "International URIs". Thanks. Jon Noring
