RE: Last Call: draft-levin-mmusic-xml-media-control (XML Schema for Media Control) to Informational RFC

Hi Pete,

After consulting with my co-authors our view is that industry implemented the solution as specified in the example, so we need to revise the schema based on Pete's suggestion to

<?xml version="1.0" encoding="utf-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" id="TightMediaControl">

<xs:element name="media_control">

<xs:complexType>

<xs:sequence>

<xs:element name="vc_primitive" type="vc_primitive" minOccurs="0" maxOccurs="unbounded"/>

<xs:element name="general_error" type="xs:string" minOccurs="0" maxOccurs="unbounded"/>

</xs:sequence>

</xs:complexType>

</xs:element>

<xs:complexType name="vc_primitive">

<xs:sequence>

<xs:element name="to_encoder" type="to_encoder"/>

<xs:element name="stream_id" type="xs:string" minOccurs="0" maxOccurs="unbounded"/>

</xs:sequence>

</xs:complexType>

<!-- Encoder Command:

Picture Fast Update

-->

<xs:complexType name="to_encoder">

<xs:choice>

<xs:element name="picture_fast_update"/>

</xs:choice>

</xs:complexType>

</xs:schema>

This also means that we will not have the target name space so we do not need to register it with IANA as specified in section 9.2.

<xs:complexType name="vc_primitive">

<xs:sequence>

<xs:element name="to_encoder" type="to_encoder"/>

<xs:element name="stream_id" type="xs:string" minOccurs="0" maxOccurs="unbounded"/>

</xs:sequence>

</xs:complexType>

<!-- Encoder Command:

Picture Fast Update

-->

<xs:complexType name="to_encoder">

<xs:choice>

<xs:element name="picture_fast_update"/>

</xs:choice>

</xs:complexType>

</xs:schema>

This also means that we will not have the target name space so we do not need to register it with IANA as specified in section 9.2.

If this is correct I will submit a revised revsion.

Thanks

If this is correct I will submit a revised revsion.
