+## xml.symbols.maxItemsComputed
+
+Use `xml.symbols.maxItemsComputed` to limit the number of symbols that are computed for each XML document.
+This helps to prevent cases where the extension runs out of memory on large documents.
+This limit can also improve performance on large documents.
+
+The default limit is 5000.
+If the limit is set to 0, no symbols are computed.
+If the limit is set to a negative number, all the symbols will be computed.
+
+If `xml.symbols.showReferencedGrammars` is enabled, the referenced grammar symbols are included in the count.
+If symbols are disabled, this setting has no effect.
