Suppose I have a sequence. It has an infix separator which is "=". <sequence dfdl:separator="=" dfdl:separatorPosition="infix"> <element name="a" type="xs:string"/> <element name="b" type="xs:string"/> </sequence> Now, consider this data: password=f82+=7&%q I want <a>password</a> <b>f82+=7&%q</b> Notice how the b element contains an '=' which was not escaped in any way in the sequence. Element b is statically known to be last, the separator is infix; hence, things are unambiguous even if there is no escaping. However, there is an alternative interpretation, which is that the above data should fail, because it produces <a>password</a><b>f82+</b> but then does not find the expected stuff next. Rather it finds the '=7&%q' data. In other words, the sequence separator divides the sequence content into 3 content regions, but there aren't 3 things to consume those, so it is a processing error.
