Hi Jirka, Tara, Indeed PIs allow ampersand to be entered directly. However, the xml-model spec refers to the xml-stylesheet spec for pseudo-attributes http://www.w3.org/TR/2010/REC-xml-stylesheet-20101028/#dt-pseudo-attribute and that specifies that the presudo-attribute value should be obtained after processing character entities and predefined entities by replacing them with the corresponding characters: *** [Definition: The string matched by PseudoAttValue in the PseudoAtt production — with the three modifications specified below — constitutes the value of the corresponding pseudo-attribute.] Each CharRef is replaced with the character it represents according to XML [XML]. Each PredefEntityRef in PseudoAttValue is replaced with U+0026 (&) if it is "&", U+003C (<) if it is "<", U+003E (>) if it is ">", U+0022 (") if it is """ and U+0027 (') if it is "'". The first and last character (the start and end quotes) are removed. *** So, we should make sure we have this processing added to oXygen.

If the value of the @href attribute of an xml-model processing instruction is a URL with query string, the ampersands in the query string must be replaced with& to avoid an error. This is as it should be.
No, entity references are not recognized inside processing instructions so& has to be entered directly withou escaping.
