<!--

-->
<!--
* This DTD forms part of the SCA Assembly Test Suite.
* It declares a number of XML Entities which are used in Entity References in
some of the
* composites that are artifacts used in the testcases.
*
* The values declared in the Entity References are intended to reflect SCA
runtime specific
* values for certain aspects of the composites at runtime - in particular
addresses of some
* services.
*
* It is permitted - indeed it is expected - that an SCA runtime provider will
MODIFY the values
* declared for the Entity References to match the values which would be
expected when running the
* SCA Assembly test suite against a given SCA runtime. The values held in the
this file are
* examples, derived from running the test suite against the Apache Tuscany SCA
runtime.

> Key: TUSCANY-3548
> URL: https://issues.apache.org/jira/browse/TUSCANY-3548
> Project: Tuscany
> Issue Type: New Feature
> Components: Java SCA Core Runtime
> Affects Versions: Java-SCA-2.0-M4
> Reporter: Mike Edwards
> Assignee: Mike Edwards
> Fix For: Java-SCA-Next
>
>
> Currently, processing of SCA composite files ignores any content that appears
> before the <composite> element.
> In particular, this means that any DTD declarations and any Entity
> Declarations within a DTD are simply ignored.
> This prevents the parameterization of composite files using Entity References.
> This Issue calls for the enhancement of the SCA runtime to support DTD
> declarations and Entity Declarations and so support the use of Entity
> References within composite files.
