我们目前支持以下抽象布局

file =
    xml_version (package)*

package =
    "<ecore:Package" ... "name" "=" string ">"
        (annotation | package | classifier)*
    "</ecore:Package>"

classifier =
    "<eClassifiers"
        "xsi:type" "=" string
        "name" "=" string
        "abstract" "=" string
    ">"
        (annotation | operation | structural_feature)
    "</eClassifiers>

annotation =
    "<eAnnotations"
        "source" "=" string

        ( "<details" "key" "=" string "value" "=" string ">" )*
