It would be desirable to have the following milestones to merge this pull request:

• Install this schema as the profiles XSD done in src/fastrtps/CMakeLists.txt line 542
• Include system test as the profiles XSD done in src/fastrtps/test/system/tools/fastdds/CMakeLists.txt with all xml documents with the sufix *_static_disc.xml, and include it in the tests.py file

Note: the CLI command fastdds xml validate would be used. It automatically uses the profiles schema, but adding -x path/to/installed/static_discovery/schema.xsd would validate the given *_static_disc.xml files against the given schema.

Blackbox tests include some XML files that require a previous CMake configuration (for instance test/blackbox/PubSubreader_static_disc.xml.in). It would be nice to configure and validate them as well.
