An infinite loop when loading xsi?

Hi there! I am now trying coding AppxManifest.xml manually. My current xml is like:

And an error occurred in <Extensions>:

Current configuration of the parser doesn't allow the expansion of a content model for a complex type to contain more than 163,840,000 nodes.

I have set -Djdk.xml.maxOccur=163840000 -Xmx8G.

Although the above xml has an enormous xsi, I don't think it has more than one hundred million nodes. I guess that the LSP is in an infinite loop.

Anyone has any idea?

Note: There are two <Extensions> element sharing the same name. One is CT_ApplicationExtensions, the other one is CT_PackageExtensions. Maybe relative with this issue?

Reproduce the report in VS Code with the supplied AppxManifest.xml, focusing on xsi:schemaLocation expansion and the two Extensions elements. Start at the XML language server's parser entry point and trace the complex-type content-model expansion until the node limit is reached. Done means the manifest no longer enters runaway expansion and valid diagnostics remain available.
