/package/requirements

There are three different requirement types:

- The `<packages>` section lists CMSIS Packs that have been used to configure the project. This includes the specification of a `version` range to ensure compatibility. If no version is provided, the latest installed version is used. If not yet installed, the latest available version will be installed before resolving the configuration.
- The `<compilers>` section specifies the toolchains that are supported by this example. The required compiler version is specified using the `version` element. If no compiler is specified, it is assumed that any toolchain will work.
- The `<languages>` section allows to specify requirements regarding the programming language, for example C99 standard. If no language requirements are set, ANSI C is assumed.

Example requirements section:

<package xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="PACK.xsd"/>
...
<requirements>
<packages>
<package name="STM32F4xx_DFP" vendor="Keil" version="2.8.0:2.8.0"/>
</packages>
<compilers>
<compiler name="ARMCC" version="5.0.0:5.99.0"/>
</compilers>
<languages>
<language name="C" version="99"/>
</languages>
</requirements>
...
</package>
