# Choosing a software package

Saxon is distributed in three packages: Saxon-HE, Saxon-PE, and Saxon-EE, each of which is available for both the Java and .NET platforms. Saxon-HE is available under an open-source license (specifically, the Mozilla Public License), and all its features are available to all users. Saxon-PE and Saxon-EE are commercial products and require activation by a license key.

There are also restricted licenses that work with Saxon-EE but restrict its capability:

- The EET license provides schema validation and schema-aware XSLT transformation only (no XQuery)

- The EEQ license provides schema validation and schema-aware XQuery only (no XSLT)

- The EEV license provides schema validation only (no XQuery or XSLT)
