If "foo" is an *internal* entity, the spec clearly requires your parser to expand it for the application. But letting the app know that the ref was encountered is also fine. However, the spec says nothing that would require you to merge the text from a variety of entities. For example, Lark's event-stream API will generate a series of Text object events in just this situation. On the other hand, once you've seen the end of the element, Lark has an API just to get all the text. This is strictly a matter of a design choice; as Richard points out, if you want to support a "grep" application, you'd probably like to have entity replacements merged for you. On the other hand, if you're building a full-text index, you probably need to have the separate chunks made visible so that you know what to point at from the index. As James has pointed out more than once, there is no universal document API that meets everybody's application needs. One of the nice things about XML is that if you can't find a parser that has the API you need, you can go build your own without excessive pain. -Tim xml-dev: A list for W3C XML Developers.
