ATEX hypertext cross-references
Anything which can be referenced advances some counter; we overload this to put in a hypertext starting point (with no visible anchor), and make a note of that for later use in
\label. This will fail badly if\theH<name>does not expand to a sensible reference.
This means that classes or package which introduce new elements need to define an equiv- alent\theH<name>for every\the<name>. We do make a trap to make\theH<name>
be the same as\arabic{<name>}, if\theH<name>is not defined, but this is not neces- sarily a good idea. Alternatively, the ‘naturalnames’ option uses whatever LATEX provides, which may be useable. But then its up to you to make sure these are legal PDF and HTML names. The ‘hypertexnames=false’ option just makes up arbitrary names.
All the shenanigans is to make sure section numbers etc are always arabic, separated by dots. Who knows how people will set up\@currentlabel? If they put spaces in, or brackets (quite legal) then the hypertext processors will get upset.
But this is flaky, and open to abuse. Styles likesubeqnwill mess it up, for starters.
Appendices are an issue, too. We just hope to cover most situations. We can at least cope with the standard sectioning structure, allowing for\partand\chapter.
Start with a fallback for equations

Tanmoy asked for this default handling of undefined\theH<name> situations. It re- ally isn’t clear what would be ideal, whether to turn off hyperizing of unknown ele- ments, to pick up the textual definition of the counter, or to default it to something like
\arabic{name}. We take the latter course, slightly worriedly.

29 Package lastpage support
Package lastpage directly writes the\newlabelcommand to the aux file. Because pack- age hyperref requires additional arguments, the internal command\lastpage@putlabel is redefined. The patch is deferred by \AtBeginDocument, because it is possi- ble that package lastpage is loaded after package hyperref. The same algorithm (options hypertexnames and plainpages) is used to get the page anchor name as in
\Hy@EveryPageAnchor (see sec. 38). The link will not work if option pageanchor is set to false.

34 Equations
We want to make the whole equation a target anchor. Overload equation, temporarily reverting to original \refstepcounter. If, however, it is in AMS math, we do not do anything, as the tag mechanism is used there (see section41). The execption is that we
move the equation incrementation inside the math environment to avoid specials outside and a wrong vertical spacing of equation environments.

My goodness, why can’t LATEX be consistent? Why is\eqnarrayset up differently from other objects?
People (you know who you are, Thomas Beuth) sometimes make an eqnarray where allthe lines end with\notag, so there is no suitable anchor at all. In this case, pass by on the other side.
