All reports of capitalization-error-in-description for the archive. The extended description of this tag is:
Lintian found a possible capitalization error in the package description. Lintian has a list of common capitalization errors, primarily of upstream projects, that it looks for. It does not have a dictionary like a spelling checker does.
This is a particularly picky check of capitalization in package descriptions, since they're very visible to end users, but it will have false positives for project names used in a context where they should be lowercase, such as package names or executable names.
This tag has not been emitted in any package tested by Lintian.
