<h1>🔍 FML Syntax Validation Endpoint</h1>

<p>Implementation of FML (FHIR Mapping Language) syntax validation endpoint as requested in the issue. This provides detailed error messages with line and column information for debugging FML syntax errors.</p>

<div class="demo-section">
<h2>✅ Valid FML Example</h2>
<div class="example">
<h3>Input FML:</h3>
<div class="result valid">map "http://example.org/fhir/StructureMap/PatientTransform" = "PatientTransform"

uses "http://hl7.org/fhir/StructureDefinition/Patient" alias Patient as source
uses "http://example.org/StructureDefinition/MyPatient" alias MyPatient as target

group Patient(source src : Patient, target tgt : MyPatient) {
src.name -> tgt.name;
src.gender -> tgt.gender;
}</div>
<h3>Validation Response:</h3>
<div class="result valid">{
"resourceType": "OperationOutcome",
"issue": [
{
"severity": "information",
"code": "informational",
"diagnostics": "FML syntax is valid"
}
]
}</div>
</div>
</div>

<div class="demo-section">
<h2>❌ Invalid FML Example</h2>
<div class="example">
<h3>Input FML (with syntax errors):</h3>
<div class="result invalid">// Missing map declaration
uses "http://hl7.org/fhir/StructureDefinition/Patient" alias Patient as source

group Test(source src {
// Missing closing paren and brace
}</div>
<h3>Validation Response:</h3>
<div class="result invalid">{
"resourceType": "OperationOutcome",
"issue": [
{
"severity": "error",
"code": "invalid",
"diagnostics": "FML content must start with a map declaration",
"location": ["line 1, column 1"]
}
]
}</div>
</div>
</div>

<div class="demo-section">
<h2>🚀 API Usage</h2>
<div class="example">
<h3>REST API Endpoint:</h3>
<div class="curl-example">POST /api/v1/fml/validate-syntax

curl -X POST http://localhost:3000/api/v1/fml/validate-syntax \
-H "Content-Type: application/json" \
-d '{"fmlContent": "map \"test\" = \"Test\""}'</div>

<h3>MCP Tool:</h3>
<div class="curl-example">Tool: validate-fml-syntax
Input: {"fmlContent": "map \"test\" = \"Test\""}</div>
</div>
</div>

<div class="demo-section">
