I paste here what I obtain using either tex2lyx (1.4.0pre3) or reLyX (1.3.7).

Prime equation numbers
\layout Standard
First an equation.
\begin_inset Formula \begin{equation} \label{e:previous}
A=B
\end{equation}
\end_inset
That was equation
\latex latex
\backslash eqref{e:previous}
\latex default
.
\layout Standard
Then the same, with a prime on the number.

\newline
\latex default
\begin_inset Formula \begin{equation}
\tag{\ref{e:previous}\('\)}\label{e:prevprime}

\end{equation}
\end_inset
And that was equation
\latex latex
\backslash eqref{e:prevprime}
\latex default
.
\layout Standard
Notice, by the way, that when a
\latex latex
\backslash verb"
\backslash ref"
\latex default
occurs inside a
\latex latex
\backslash verb"
\backslash tag"
\latex default
, and that
\latex latex
\backslash verb"
\backslash tag"
\latex default
is then
\latex latex
\backslash verb"
\backslash label"
\latex default
'd, a
\latex latex
\backslash verb"
\backslash ref"
\latex default
for the the second
\latex latex
\backslash verb"
\backslash label"
\latex default
requires
\emph on
three
\emph default
runs of LaTeX in order to get the proper value.
(If you run through the logic of LaTeX's cross-referencing mechanisms as they
apply in this case, you will see
that this is necessary.)
\layout Section
Subnumbered equations
\layout Standard
Here is a,b,c sub-numbering.
\latex latex
\backslash begin{subequations}
\newline
\backslash begin{eqnarray}
\newline
A&=&B
\backslash
\backslash
\newline
D&=&C
\backslash label{e:middle}
\backslash
\backslash
\newline
E&=&F
\newline
\backslash end{eqnarray}
\newline
\backslash end{subequations}
\latex default
That was produced with the
\latex latex
\backslash env{eqnarray}
\latex default
environment; the middle line was labeled as
\latex latex
\backslash eqref{e:middle}
\latex default
.
\layout Standard
An equation following the end of the
\latex latex
\backslash verb"subequations"
\latex default
environment should revert to normal numbering:
\begin_inset Formula \begin{equation} \label{e:check}
H<K
\end{equation}
\end_inset
A check on the labeling: that was equation
\protected_separator
\latex latex
\backslash eqref{e:check}
\latex default
.
\layout Standard
The sub-numbered equations can be spread out through the text, like this:
\latex latex
\backslash begin{subequations}
\newline
\backslash begin{equation}
\newline
A=B
\newline
\backslash end{equation}
\newline
The
\backslash verb"subequations" environment can span arbitrary text between
\newline
subsidiary equations. The only restriction is that if there are any
\newline
numbered equations inside the
\backslash verb"subequations" environment that break
\newline
out of the subequation numbering sequence, they would have to be handled
\newline
specially.
\newline
\backslash begin{equation}
\newline
D=C
\backslash label{e:newmiddle}
\newline
\backslash end{equation}
\newline
More arbitrary text.
\newline
\backslash begin{equation}
\newline
E=F
\newline
\backslash end{equation}
\newline
\backslash end{subequations}
\latex default
Label check: the middle one was
\latex latex
\backslash eqref{e:newmiddle}
\latex default
\layout Standard
A final equation for a numbering check.
\begin_inset Formula \begin{equation} \label{e:final}
G=H
\end{equation}

That equation was labeled as
