Azure AD B2C自定义策略<ClaimsTransformations>架构验证错误求助

上传Azure AD B2C自定义策略时，持续遇到与<ClaimsTransformations>部分相关的架构验证错误，错误信息不固定，但常见提示：

命名空间'http://schemas.microsoft.com/online/cpim/schemas/2013/06'中的元素'ClaimsTransformation'包含无效子元素'InputClaims'，预期元素为'OutputClaims'。

关键细节 #

• 错误指向的行不固定，但始终提示某些转换方法中<InputClaims>是无效子元素
• 已确认CopyClaim、FormatStringMultipleClaims、BuildUri等方法按文档要求使用<InputClaims>和<OutputClaims>
• CreateOtpSecret、CreateStringClaim、FormatStringClaim等方法仅使用<OutputClaims>（必要时搭配<InputParameters>），未使用<InputClaims>
• 即便XML符合架构规范，错误仍持续出现

已尝试操作 #

• 反复检查所有<ClaimsTransformation>块，确认<InputClaims>、<OutputClaims>、<InputParameters>使用正确
• 移除了不支持<InputClaim>的转换方法中的对应元素
• 验证XML结构，确保无重复或错位元素
