Anchor based tagging
This section outlines the usage rules and behaviors of the Docusign Anchor-Based Tagging feature. Anchor-Based Tagging enables a Docusign customer to send documents for signature that do not have a fixed layout or format. In these documents, you can not anticipate the absolute location of the tabs when you design your API client application because the tabs must move with text. As an alternative to sending X and Y coordinates for tabs, the Docusign Signing Service derives anchor tab locations by correlating XML instructions from the SOAP request to data within the document.
