+% \section{Support for theorems} 
+% 
+% Hyperlink support in theorems has to resolve typically three problems:
+% \begin{itemize}
+% \item The \cs{refstepcounter} can be issued to early. The target it produces
+% can be separated from the theorem and then the link if wrong (see testfiles thm-005-xx). 
+% It can also affect spacing. 
+% This means that it is better if this \cs{refstepcounter} doesn't produce a target.
+%
+% \item The natural place for the target (before the theorem label) is normally not printed
+% directly but delayed to the next paragraph begin (through the \cs{item} code or by other means). 
+% and \cs{label} commands used directly at the begin of the environment are perhaps 
+% processed \emph{before} the target is created 
+% and so do not know the correct \cs{@currentHref} value. That means that if
+% \cs{refstepcounter} does not produce a target, it should nevertheless update the target
+% name.
+% 
+% \item The target should be placed (in horizontal mode) before the theorem label to avoid
+% side effects on spacing. For this a suitable place must be 
+% found depending on the actual theorem definition. 
+% \end{itemize} 
+% 
+% Theorems typically issue the \cs{refstepcounter} in \cs{@thm}. 
+% The first two points can therefore be resolved by patching this command 
+% and replacing the \cs{refstepcounter}. 
+% 
+% The last point is the most complicated. Simply moving at the point \cs{refstepcounter}
+% is encountered into the next para hook doesn't work, as this can be in a header if there is page
+% break. The next item hook doesn't work for the same reason, 
+% also not every theorem environment actually use \cs{item} (e.g. \xpackage{amsthm} and ams-classes).
+% Patching (or using a hook) \cs{@begintheorem} doesn't work either as \xpackage{ntheorem}
+% redefines this on the fly. 
+% 
+% For now we move the target creation into the item hook. This is not perfect,
+% as it can end up in header or be to much to the right, but there is not really
+% a better place.
+% 
+% The patch will not apply to 
+% \texttt{cleveref}, this means that with cleveref there
+% can be a page break between target and theorem but beside this
+% it hopefully it does the right thing.
 % \cs{@currentHref} is updated directly for labels set before 
 % the actual start of the paragraph. The target can be behind
 % a target created from a following list, so we restore \cs{@currentHref}
