Aspire allows "if" tags in your html pages. Here is an example.
<!--RLF_TAG BGN_IF aspire_key_name=literal_value if1 -->
<!--RLF_TAG END_IF aspire_key_name=literal_value if1 -->
Aspire will take the "aspire_key_name" and try to locate it in the aspire data set. If it is there its value is taken and compared to the literal_value. The key is not case sensitive but the values are. If the strings are the same (or match) then the html segment will be included in the page otherwise not.
