The Altova Schema Manager provides a centralized way to install and manage industry-standard DTDs and XML Schemas (XSDs) for use across all Altova XML-enabled applications. You may access the Altova Schema Manager from within your installed Altova products or via this page.
Altova will update available schema versions frequently when they are released from standards bodies - you may download them here independent of any product release cycle.
Please select the XML schemas you would like to download from the list below.
Any required dependencies will be selected automatically.
