A deprecation notice is advisory, not a validation failure, but hasProblems() counted it like any other problem. So a deprecated branch of an anyOf/oneOf that actually matched the value was treated as a non-match, and a non-matching sibling was reported instead (e.g. a const branch's 'Value is not accepted' message). The const case happened to work only because enumValueMatch is a separate tiebreaker; a pattern branch had no such luck. Exclude deprecation problems from hasProblems() so match selection ignores them. The deprecation diagnostic is still reported. Fixes microsoft#304

Fixes #304.
In an
anyOf/oneOf, a branch that actually matches the value but is markeddeprecatedwas treated as a non-match, so a non-matching sibling got reported instead. With the schema from the issue,"text value"matches thepatternbranch, but the hover/validation showedValue is not accepted. Valid values: "unused literal".instead ofValue is deprecated.The cause is that the deprecation notice is pushed as a problem, and
ValidationResult.hasProblems()counted it like a validation error when selecting the best alternative. Theconstcase in the issue only worked by luck —enumValueMatchis a separate tiebreaker incompare(); apatternbranch has nothing equivalent, so the deprecated-but-matching branch lost.Fix: exclude deprecation problems from
hasProblems()(they're advisory,severity: Warning,code: ErrorCode.Deprecated). Match selection now ignores them, while the deprecation diagnostic itself is still reported.Added a test in
parser.test.tscovering the issue's schema (matching value →Deprecated; non-matching value → the non-match error, unchanged). Fullparser.test.jspasses;jsonSchemaTestSuitefailure count is unchanged frommainon my machine (pre-existing URN cases).
