XLIFF Manager can validate XLIFF 1.0,
1.1, 1.2 and 2.0.
Validating XLIFF against XML grammars (DTD or XML Schemas) is not enough. XML Schema
validation does not detect the use of duplicated 'id' attributes, wrong language
codes and other constraints written in the different XLIFF specifications.
In addition to validating all XLIFF 2.0 modules using XML Schema validation, extra
validation is performed for XLIFF 2.0 Core and for Metadata, Matches and Glossary
modules.
Procedure
In main menu, select View → Validate XLIFF or click the Validate XLIFF option on the left
panel.
Type the name and location of the XLIFF file to validate in the
XLIFF File text box or click the
Browse... button to select an XLIFF file from the
file system.
