The actual data and navigational elements in exported models are marked with special markers called Replace Tags. Most of the tags have a very specific behavior, and many of them are required for the views to function properly. Every Replace Tag is marked as <#ReplaceTagName>, where ReplaceTagName represents a predefined Replace Tag for the view. Some replace tags may also require parameters, like <#CompanyImage Location="Default" CompanyLogo="QPRLogo.jpg">.
Note that QPR Portal uses also other replace tags than those listed here, but they are not described here due to complex usage.
