What standards does lxml implement?
The compliance to XML Standards depends on the support in libxml2 and libxslt. Here is a quote from http://xmlsoft.org/: In most cases libxml2 tries to implement the specifications in a relatively strictly compliant way. As of release 2.4.16, libxml2 passed all 1800+ tests from the OASIS XML Tests Suite. lxml currently supports libxml2 2.6.20 or later, which has even better support for various XML standards. The important ones are: • XML 1.0 • HTML 4 • XML namespaces • XML Schema 1.0 • XPath 1.0 • XInclude 1.0 • XSLT 1.0 • EXSLT • XML catalogs • canonical XML • RelaxNG • xml:id • xml:base Support for XML Schema is currently not 100% complete in libxml2, but is definitely very close to compliance. Schematron is supported, although not necessarily complete. libxml2 also supports loading documents through HTTP and FTP.

Schematron is supported in two ways, the best being the original ISO Schematron reference implementation via XSLT. libxml2 also supports loading documents through HTTP and FTP.
