Hi, I’m confused by the R4 core spec. section 3.5.5, Export-Package Header (and also the import-package header), it says:
Export-Package ::= export ( ’,’ export )* export ::= package-names ( ’;’ parameter )* package-names ::= package-name // See 1.4.2 ( ';' package-name )* The header allows many packages to be exported. An export definition is the description of a single package export for a bundle. Multiple export definitions for the same package are allowed for example, when different attributes are needed for different importers. So what does an ”export definition” really mean? According to the syntax, I can write this: 1) Export-Package: foo, bar;version=1.0.0 and 2) Export-Package: foo; bar;version=1.0.0, bar;version=1.0.1 As we know in case 1 the version attribute is only applied to package bar, and in case 2, it applied to both foo and bar, right? OK, the question is: how many export definitions are there in case 1 and 2? My thought is that in case 1, there are two export definitions: foo with default version 0.0.0 and bar with version 1.0.0; in case 2, there are three export definitions, foo with version1.0.0, bar with version 1.0.0, and bar with version 1.0.1. Am I right? Thanks! Fei
