• Remove all string arrays from source and replace them by auto-expandable strings
• type checking for attributes
• Programmable error output format (to be parsed by editor)
• NULL value for attributes
• <$IF ..> tag for conditional conversion
• <$LET ..> tag to define global attributes
• Handle "Click here"
• Strip tags when referencing to an external link (NoNet-version)
• CLI-option to strip useless empty lines

Far future

• Test named references
• Automatically add <LINK REL="subdocument" HREF="..">

• Fully support creation of a NoNet-version
• CLI-option to act like a html2asc-tool (only if I'm bored)
