PSVI is an acronym for Post-Schema-Validation Infoset, a term used in XML parsing.

Main article: XML Schema

Briefly, an XML schema assigns an identifiable type to each element. Validating an XML document against this schema produces a Post Schema Validation Infoset, PSVI for short, where each element, attribute and in general, any node of the XML document has assigned the type from XML schema. Schema-aware applications using schema parsers and APIs can make use of the types of elements.
