+# XML Schema Documentation: RBCS Client Configuration
+
+This document provides detailed information about the XML schema for RBCS client configuration, which defines profiles for connecting to RBCS servers.
+
+## Root Element
+
+### `profiles`
+The root element that contains a collection of server profiles.
+- **Type**: `profilesType`
+- **Contains**: Zero or more `profile` elements
+
+## Complex Types
+
+### `profilesType`
+Defines the structure for the profiles collection.
+- **Elements**:
+    - `profile`: Server connection profile (0 to unbounded)
+
+### `profileType`
+Defines a server connection profile with authentication, connection settings, and retry policies.
+
+- **Attributes**:
+    - `name` (required): Name of the server profile, referenced with the '-p' parameter in rbcs-cli
+    - `base-url` (required): RBCs server URL
+    - `max-connections`: Maximum number of concurrent TCP connections (default: 50)
+    - `connection-timeout`: Timeout for establishing connections
+    - `enable-compression`: Whether to enable HTTP compression (default: true)
+
+- **Elements** (in sequence):
+    - **Authentication** (choice of one):
+        - `no-auth`: Disable authentication
+        - `basic-auth`: Enable HTTP basic authentication
+        - `tls-client-auth`: Enable TLS certificate authentication
+    - `connection` (optional): Connection timeout settings
+    - `retry-policy` (optional): Retry policy for failed requests
+    - `tls-trust-store` (optional): Custom truststore for server certificate validation
+
+### `connectionType`
+Defines connection timeout settings.
+
+- **Attributes**:
+    - `idle-timeout`: Close connection after inactivity period (default: PT30S - 30 seconds)
+    - `read-idle-timeout`: Close connection when no read occurs (default: PT60S - 60 seconds)
+    - `write-idle-timeout`: Close connection when no write occurs (default: PT60S - 60 seconds)
+
+### `noAuthType`
+Indicates no authentication should be used.
+- No attributes or elements
+
+### `basicAuthType`
+Configures HTTP Basic Authentication.
+
+- **Attributes**:
+    - `user` (required): Username for authentication
+    - `password` (required): Password for authentication
+
+### `tlsClientAuthType`
+Configures TLS client certificate authentication.
+
+- **Attributes**:

+    - `key-store-password` (required): Password to open the keystore
+    - `key-alias` (required): Alias of the keystore entry with the private key
+    - `key-password` (optional): Private key entry's encryption password
+
+### `retryType`
+Defines retry policy using exponential backoff.
+
+- **Attributes**:
+    - `max-attempts` (required): Maximum number of retry attempts
+    - `initial-delay`: Delay before first retry (default: PT1S - 1 second)
+    - `exp`: Exponent for computing next delay (default: 2.0)
+
+### `trustStoreType`
+Configures custom truststore for server certificate validation.
+
+- **Attributes**:
+    - `file` (required): Path to the truststore file
+    - `password`: Truststore file password
+    - `check-certificate-status`: Whether to check certificate validity using CRL/OCSP
+    - `verify-server-certificate`: Whether to validate server certificates (default: true)
+
