LaTeX conflict between biblatex and draftmark?

Question

I need to use biblatex for a draft of a report. I'd like to use draftmark to create a water mark as well. However, the document fails to compile even with just the usepackage statements. Here is a MWE:

\documentclass[11pt,letter]{report}
\usepackage{biblatex}
\usepackage{draftmark}

\begin{document}
  Lorem ipsum dolor sit amet.
\end{document}

And I get the following error:

\file \blx@list@req@stat \advance \lrq@indent \m@ne \xappto \lrq@hook@data \ETC
Latex Error: ./untitled.tex:14 Paragraph ended before \ettl@forloop was complete.

Latex Error: ./untitled.tex:14 Extra }, or forgotten \endgroup.

pdfTeX warning: pdflatex: \pdfmatch: repetition-operator operand invalid

! Emergency stop.

! ==> Fatal error occurred, no output PDF file produced!

Any idea what's going on here or if there's a work around?

EDIT

Additionally, I would like to add a draft watermark to the bottom of the page, in the footer area (so that it's easier to others to read).

Answer 1

Since draftmark uses etextools and biblatex applies macros from etoolbox, the usage of both packages in the same document is hopeless -- they do not match.

A similar watermark for content can be achieved with Gonzalo Medina's background package, which is quite easy to configure, however, there's no draft feature. Please note, that the package usage requires two compilation runs to get the underlying tikz anchors correct, but this is no issue, since most documents need two runs.

\documentclass[11pt]{report}
\usepackage{biblatex}


\usepackage{background}
\usepackage{blindtext}


\backgroundsetup{contents=DRAFT,color=blue}

\begin{document}
  \blindtext[5]
\end{document}

Edit A small 'hack' to use the draft option of the report.cls

\documentclass[11pt,draft]{report}
\usepackage{biblatex}

\usepackage{blindtext}

\newif\ifdraftmode  % Define the `\ifdraftmode` conditional
\draftmodefalse     % Set it to false --> not the draft mode

\DeclareOption{draft}{\draftmodetrue\setlength\overfullrule{5pt}} % set draft mode to true if specified
\ProcessOptions*  % Reprocess options

\ifdraftmode                   % Check for draftmode
\usepackage{background}        % Within the check, because the package automatically sets a pink coloured 'Draft' in the background
\backgroundsetup{angle=0,scale=3,placement=bottom,vshift=0.5cm,contents=DRAFT,color=blue} 
\fi


\begin{document}
\blindtext[5]
\end{document}
