For an XPath 1.0 string literal embedded in an XML attribute, the rule is: * you can include the attribute delimiter within the string literal by using an XML character reference * you can't include the string literal delimiter within the string literal, however hard you try So the simplest approach if you want to use apos within a string literal is to use apos as the attribute delimiter, quot as the string delimiter, and ' for the character itself. It's also possible to use the same delimiter for the attribute and for the string literal provided that the latter is ampersand-escaped; in this case you can use the other delimiter unescaped within the string to represent itself. In an XSLT context, you can get around this using variables, but I don't know if that's an option in Schematron. It becomes easier with XPath 2.0, which allows the string delimiter to be escaped within the string by doubling it.
