+There is also a function to insert the literal value of a character.  Since Ur/Web uses the UTF-8 text encoding, the $\mt{cdata}$ function is only sufficient to encode characters with ASCII codes below 128.  Higher codes have alternate meanings in UTF-8 than in usual ASCII, so this alternate function should be used with them.

 There is a function for producing an XML tree with a particular tag at its root.
