## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 1462 "Xml DotNet Convert"](../codeunit/1462.md) (5 calls: `AddClause → ToDotNet`, `AddObject → ToDotNet`, `GetXml → FromDotNet`, …)
- [Codeunit 1285 "X509Certificate2 Impl."](../codeunit/1285.md) (1 call: `AddKeyInfoClauseFromX509Certificate → InitializeX509Certificate`)

## Called by

- [Codeunit 1460 "SignedXml"](../codeunit/1460.md) (32 calls: `AddClause → AddClause`, `AddKeyInfoClauseFromX509Certificate → AddKeyInfoClauseFromX509Certificate`, `AddObject → AddObject`, …)

## Recent changes

- 2026-10-07 [#10212 Add SetReferenceType method to SignedXml and SignedXmlImpl (#10139)](../../changes/bcapps/10212.md) (main, BC30, feature)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24, BC27-28, BC30

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "SignedXml Impl.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
