Approach:
1. Task: Create experiment result in XML
2. Complexity: simple - 3-5 fields, minimal nesting
3. Format rules: well-formed tags, proper nesting, escaped special chars
4. Structure: Organize data logically with appropriate nesting
5. Populate fields with realistic example data based on the schema.

Output:
<?xml version="1.0" encoding="UTF-8"?>
<experiment_result>
<methodology>
<design>RCT</design>
<sample_size>193</sample_size>
<duration_days>365</duration_days>
</methodology>
<experiment_id>EXP-345048</experiment_id>
<conclusion>significant</conclusion>
</experiment_result>
