# [DRILL-8453](https://issues.apache.org/jira/browse/DRILL-8453): Add XSD
Support to XML Reader (Part 1)
## Description
This PR is a part of a series to add better support for reading XML data to
Drill. One of the main challenges is that XML data does not have a way of
inferring data types, nor does it have a way of detecting arrays.
The only way to do this really well is to have a schema. Some XML files
link a schema definition file to the data. This PR adds the capability for
Drill to map XSD schema files into Drill schemas.
The current plan is as follows: Part 1 of this PR simply adds the reader but
adds no new user detectable functionality. Part 2 will include the actual
integration with the XML reader. Part 3 will include the ability to read
arrays.
## Documentation
No user facing changes.
## Testing
Added new unit tests.
