I got from our customer some formula blocks which does not worked:
<ac:structured-macro ac:name="mathblock" ac:schema-version="1" ac:macro-id="cc39412b-fa59-4457-ae27-27dc3aa1c2a5"><ac:plain-text-body><![CDATA[T_{\mathrm{out}} = T_{\mathrm{GasImBehälter}} \tag{2}]]></ac:plain-text-body></ac:structured-macro> <ac:structured-macro ac:name="mathblock" ac:schema-version="1" ac:macro-id="9fa30898-28f0-4365-a049-c8fc6eba3bec"><ac:plain-text-body><![CDATA[p(t) \cdot V = m(t) \cdot R \cdot T \tag{3}]]></ac:plain-text-body></ac:structured-macro> <ac:structured-macro ac:name="mathblock" ac:schema-version="1" ac:macro-id="921b0205-83cf-4f5d-a4ca-a43eb3a869dc"><ac:plain-text-body><![CDATA[\frac{\mathrm d}{\mathrm dt} p(t) = \frac RV \cdot \frac{\mathrm d}{\mathrm dt} m(t) \cdot T \tag{3.1}]]></ac:plain-text-body></ac:structured-macro> <ac:structured-macro ac:name="mathblock" ac:schema-version="1" ac:macro-id="8d8c5545-c71e-4a35-8981-6bea8acc80ab"><ac:plain-text-body><![CDATA[p(t) = \frac RV \cdot T \cdot \int (\dot m_{\mathrm{in}} - \dot m_{\mathrm{out}}) \mathop{}\!\mathrm dt \tag{3.2}]]></ac:plain-text-body></ac:structured-macro>
