我有 XSD，它在模式生成期间给出了以下错误。

    org.xml.sax.SAXParseException; systemId: file:/D:/Basil/Projects/myproducts.xsd; lineNumber: 577; columnNumber: 50; cos-all-limited.1.2: An 'all' model group must appear in a particle with '{'min occurs'}' = '{'max occurs'}' = 1, and that particle must be part of a pair which constitutes the '{'content type'}' of a complex type definition.

相关的 XSD 粘贴在下面。我无法理解实际的错误是什么。错误在倒数第三行。请帮忙。

maxOccurs="unbounded"只需摆脱<xs:group ref="prodVar" minOccurs="0" maxOccurs="unbounded" />

在 XSD 1.0 中， anxs:all不能重复（这里间接地，有些人可能会说 'nice try!'），也不能在 下的任何粒子xs:all，也不能嵌套在任何其他合成器下。
