Location information for tags

I am using this package in the open PHP language server, which provides static analysis for any IDE through the open language server protocol. One of these features is "Go to Definition". This is currently implemented for the actual PHP code through nikic's great PHPParser, where every node has a file start/end offset so I can calculate which node the user clicked. It would be nice to have this feature for types in docblock tags like @var too, but the tags don't have any start/end offset data. Would it be possible to add this?

Issue 中没有提到任何文件或测试。首先定位 @var 和其他 docblock 标签的解析方式，并将它们的元数据与 PHPParser 节点进行比较。定义应如何公开标签的起始和结束偏移量，然后验证类型标签能够提供可用的位置信息，同时不破坏现有的解析。
