And also for containing Oleg. I hope they can provide us with their opinion on whether this is an actual bug or was designed that way. To me, it's not clear whether html->sxml should alterate the raw value of attributes in any way. Users may haev different use cases requiring to apply different transformation themselves? If we hard-code a decoding scheme ourselves, then force that choice onto users, no? -- Thanks, Maxim
