Hi, We have updated our XML filings to comply with the new CompanyIncorporation-v3-8.xsd schema, including the new `` element as specified. However, when submitting the XML, we receive the following error: ```auto Error Raised By: CompanyIncorporation / Number: 9999 / Type: fatal / Location: / No element 'MemorandumPersonalAuthentication' in class CompaniesHouse::Filing::PersonalAuthentication ``` This suggests our filing is not being validated against the correct (latest) schema. Could you confirm if the gateway is accepting filings according to v3-8.xsd? Is there anything further we need to do to ensure the new schema is in use on your side? Thank you. ---

Hi, v3.8 has only been released as at present to give all software developers advance sight of it -it will not become live until late this year (date to be confirmed in due course). We will supply a test facility for this new schema soon. Until v3.8 becomes live, v3.7 remains the current live schema for company formation. SDN ---

I am using the test XML Gateway in order to make the necessary changes for v3.8. I am receiving this message **No element ‘MemorandumPersonalAuthentication’ in class CompaniesHouse::Filing::PersonalAuthentication’**. THe XML that I am sending seems to match the example provided on the Schema documentation page. The section of the XML I am sending is: ![image](https://xmlforum.companieshouse.gov.uk/uploads/default/original/1X/1b06fbeed878277ca0a7ed8a924e6f9ea81f6524.png) Please can you advise what I am doing wrong? ---

Hi Jeff, just to confirm what I told you via email recently - you cannot test these newly released schemas yet, we will give you a specialist way of testing these soon. ---

Hi Team, Good day! I tried testing the same on 3.8 schema. Ended up with the same error. ```auto ||| |---|---| || | || CompanyIncorporation| || 9999| || fatal| || No element 'MemorandumPersonalAuthentication' in class CompaniesHouse::Filing::PersonalAuthentication| || | || | ||| ``` (Please ignore the auto-formatting which got added) Is there any ETA on when these changes can be validated with the latest schema? Thanks ---

If you are an existing software filer with Companies House, these are the test instructions for all the schemas that come into force on 18th November: **You can use your live presenter credentials - but show Package Reference as 0012 and Test Flag as 1.** **Endpoint: [https://xmlgw-sandpit-staging.companieshouse.gov.uk/v1-0/xmlgw/Gateway](https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fxmlgw-sandpit-staging.companieshouse.gov.uk%2Fv1-0%2Fxmlgw%2FGateway&data=05%7C02%7C%7Cf23c097823614fe1637608de1a54d0f4%7Ce6acfe5e7f2a455a9d85ecf93371f601%7C0%7C0%7C638977148761655315%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=kLtgPNEMRiGYtPe1EpMrYHTl3Pg0GaH85bwD5L1pYe8%3D&reserved=0)** **If you receive an XML schema validation error, then the schema is failing due to a syntax error or incorrect basetype compatibility - and should be considered a failed test.** **If you receive any other error response, such as an authorisation failure, then that means the schema has passed the schema validation stage, and should be considered a successful test.** **For reference, the following is a link to the test service schema page.** **[https://xmlgw-sandpit-staging.companieshouse.gov.uk/SchemaStatus](https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fxmlgw-sandpit-staging.companieshouse.gov.uk%2FSchemaStatus&data=05%7C02%7C%7Cf23c097823614fe1637608de1a54d0f4%7Ce6acfe5e7f2a455a9d85ecf93371f601%7C0%7C0%7C638977148761670839%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=j6J7jfTuk6%2B1l7B%2F6FieA4sBhbjdg2vke4lsydlyYPA%3D&reserved=0)**
