Interesting question. IDs must be unique in a document per http://www.w3.org/TR/REC-xml#id. The question is, are included schemas part of the same (schema) document? It looks to me like they are: http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/#compound-schema says "The *XML Schema* corresponding to <schema> contains not only the components corresponding to its definition and declaration [children], but also all the components of all the *XML Schemas* corresponding to any <include>d schema documents."
Hmm...Denny just quoted some different sections to the same effect.
